  • Prepping a Car for Paint

    Whether you are planning on painting your car yourself, or paying to have it done, it is essential that the prep is done right. For the most part it is a time consuming job consisting of mostly grunt work, there is not really that much to learn about prepping correctly. So learn how to do it yourself, and see if you can’t knock a couple hundred off the labor bill for the next paint job at the body shop.
  • How to Select the Right Tip for Your Paint Gun

    When spraying paint with a compressed air spray gun, whether gravity feed or siphon feed, conventional or High Volume Low Pressure (HVLP), it’s important to have the gun set up properly for the job. What you are painting is important to a certain extent, but more import is what you are painting with.

    For example, if you are painting a small panel, or a motorcycle gas tank you can use a gun with a smaller spray pattern than if you are painting the side of a van.  You can still use the big gun for a small project, but it is going to be more wasteful and messy. You can use the small gun for a big job but it’s going to take a lot longer to do it.

    Moe important to the quality of the job you are doing is using a gun with the right size fluid tip and needle for the paint, primer or whatever else you are spraying. Most guns have the option of several different sized spray tip openings, with a matching needle for each one. Eastwood carries a selection of popular sizes for the guns they sell. As a general rule of thumb, thicker material, like high build primers use a bigger opening, while thinner liquids use a smaller tip.

    Often times the paint or primer will come with recommendations as to how to spray it. Usually the instructions that come with the gun will have a handy chart too. Here’s what Kevin Tetz and Eastwood recommends for the Concourse HVLP gun.

    spray gun tips

    For spraying clear coats on small parts and projects, a 1.2mm tip. For spraying a whole car a 1.3mm tip is recommended. The 1.4mm tip is perfect for base coats and metallic as the droplet size allows the particles to self-orient to eliminate streaking and mottling. The 1.8mm is at the upper end of sizes for urethane primer surfacers, and the minimum size you want to use for a poly-urethane primer surfacer, which can use up to a 2.2mm.

    Here are some common tip sizes and recommended usages:

    5 tip

    0.5-1.0mm – These are very common in detail spray guns because they provide a much smaller pattern compared to a larger tip on a full size gun. Also used for thin dyes and stains.

     

    1.2mm, 1.3mm – Good for clear coat and thinner base coats. Spraying clear with a 1.2mm will take longer because the tiny hole doesn’t flow much fluid through it but will give you a very fine finish. The 1.3mm is a great general clear coat tip, also thinner base coats, waterborne and single stage paints. Too thick of a paint won’t flow well through this size though.

    1.4mm – Great all-purpose size. Works well with most base coats, and even thicker clears. This size is the closes to a universal tip as it comes. When in doubt it’s a good place to start.

    1.5mm, 1.6mm – Versatile tip for base coats and single stage paints. Thinner paints run the risk of orange peel though because they will not atomize correctly. Also a good choice for lacquer paints.

    1.7mm, 1.8mm  –1.7mm is the smallest size you should use for most types of primer, not a very common size but currently offered on the Eastwood Concours LT Gun.  Typically 1.8mm is recommended for most primer surfacers. Also the smallest size if you are shooting latex paint, not that you would do that with your good HVLP gun.

    2.0-2.3mm – High build primers and other thick materials. Avoid spraying and base, single stage or through these size tips, it will not atomize correctly and give a poor result.

     

    pro set

    If you still are unsure what sizes you will need, Eastwood makes it easy by offering our Original Concours and Concours Pro HVLP paint guns in sets that come with multiple sizes.  Purchasing a set like these will allow you to spray all types of paints from the same gun, making it easier while saving you money.

    There you have a rundown of the common sizes of fluid tips for the HVLP spray gun and what they are for, with the most common in red. If you just remember thinner smaller, thicker bigger, it’s pretty intuitive. With fancy paints like pearls and metal flakes, you may have to go smaller and larger respectively for them to come out really well, but the only real way to find out is with practice, lots of practice.

  • Sound Deadening Paint Sprays and Mats - Benefits & Application Tips

    Cars have come a long way since WWII, but they haven’t really gotten any more enjoyable, which is why we all still like to play with our old cars. Plenty of people will argue about whether a new Honda Accord could beat a first generation Mustang in a race (it probably would, no matter whether a drag strip or a road course), but no one is going to argue about how much quieter it is inside the modern car. Sure that’s both good and bad; we want to hear the 289 roar, but that freeway drone gets old after an hour or two.
  • Can You Powder Coat Glass?

    We all know you can powder coat metal but what about other materials such as glass?  In order to powder coat an item there is really only one determining factor, it must be able to withstand 400ºF. Metal is one of the best materials to powder coat because it conducts electricity, allowing the charged powder to be drawn to the part thus completing the circuit.  That leaves out all other non conductive items, can they be powder coated too?  Hot flocking is the most common way of powder coating non conductive objects by heating them up to temperature, pulling them out of the oven and then applying the powder without needing to connect the grounding cable or plug in the gun.  The part is already hot so the powder melts on contact.  Once there is full coverage you put it back into the oven to finish curing.  This method is proven and utilized by many manufacturing companies but there are some other little known tricks to coat materials like glass without having to heat them up before.
  • Generator Buyers Guide

    Things to Consider When Shopping for a Generator

    We all like to get away from it all once in a while. Whether that is to a cabin, a remote off-road campsite, the racetrack, or just the parking lot of your favorite team’s stadium chances are there aren’t any electrical outlets handy. Having a portable generator means getting away from it all while still taking a lot of the modern conveniences with you.

    Portable generators are also great in any emergency where the power might go out. Even if you just use it to keep the refrigerator running for a few days, a generator can pay for itself after the first storm in food that didn’t go bad. Plus you’ll be able to keep your cell phones charged, and listen to the radio, or watch the TV news for important updates.

    If you live in a rural or suburban area on a big spread of land, having a generator to take out to a far corner of your homestead is easier than running hundreds of feet of extension cords just to get some work lights or run a portable compressor. The bigger units will even allow you to run a MIG welder and do portable repairs in the field, without having to haul everything back to the shop for welding.

    So, we’ve established you need a generator, so what should you consider before buying?

    (Warning: There will be math, but we won’t quiz you on it)

    1. Wattage – Generators are rated in the amount of watts they can put out, usually with a peak number and a lower continuous number. This makes it easy to figure out how many light bulbs you could run off of it, but not much else is typically rated at watts. A 3000 watt portable generator rated at 2800 continuous can light 46 lightbulbs with a 60 watt rating. For tools and appliances with an electric motor the starting wattage can be a lot higher (2 to 3 times higher) than the continuous draw, that’s why they are rated that way. Most appliances have an amperage listed in their documentation, as do most tools. The formula to convert is an easy straightforward one: Watts = Volts x Amps. So multiply the rated amperage by 120v or 240v and you get the needed wattage to run it. Our MIG 135 welder rated at 20A 120V maximum input would need 2400 watts running at full power.

    2. Voltage– The MIG 135 welder brings up a good point, if you plan on running any tools or appliances that require 220V power you had better buy a generator that puts out 220V. Of course, you already know what sort of power your tools require, but if you plan on using it for emergency backup it is important to check things like furnace and hot water heater requirements. Who cares if you can watch TV and the food is still cold when you can’t heat the house or take a hot shower?
    3. Noise – This isn’t much of an issue with emergency backup usage, as it is at campsites and the race track. If you buy a cheap generator with a loud engine that runs all night you will not have any friends in the pits or campground. Be sure to look at the Db rating of the lower cost generator before you commit because you may have to be the one listening to it all night.
    4. Pull or Electric Start?– Usually the higher wattage rated generators come with electric start, instead of just a pull cord. A pull cord is fine, and when in good order, any generator will start up with a few pulls, but the 12th time you have to start it on a week-long trip you may regret not getting the pushbutton start.
    5. Run Time – If you plan on using your generator to run lights on a job site all night, or keep the fridge cold in an emergency, you are going to want an 8hr or more run time on a tank of fuel, or you are literally going to lose sleep over it. Remember running time is usually calculated at half load, and do the math again with the formula above.
    6. Portability – This will always be a compromise, the more wattage a generator can put out the bigger it usually is. If you plan on needing power somewhere really remote and rough, and having backup for your whole house, you may need to buy 2 generators. A 7500 watt generator typically weighs close to 200lbs, which is going to require a lot of muscle to carry over an unpaved trail, even with wheels on it.
    7. Fuel – Most small to medium sized generators run on regular gasoline. But for RV usage and rural backup use diesel power is the way to go because the motors are more rugged, and diesel fuel is stable in the tank for a lot longer than modern gasoline. Some generators are configured to run on propane or LPG as well, which doesn’t produce much carbon monoxide, so can be used in tighter quarters where the fumes from a diesel or gasoline generator would make people sick.

    Eastwood’s 3000 watt generator is rated for 2800 watts of continuous usage. That will easily run most refrigerators, and a few of other appliances, as long as they don’t all start at once. Remember, anything with an electric heating element is going to be a wattage hog, a hot plate or electric griddle can use 1500 watts. We already talked about the MIG 175, but air compressor motors can suck up even more juice, especially when they first start. For example a 1hp motor can need 4500 watts to get going, so check what the motor on your portable compressor says before buying the generator.
