    • Perfectly Powder Coated Wheels- 10 Tips to Make Your Wheels Look Great

      It's a known fact that a set of wheels can make or break a car. We've seen some of the biggest "junkers" become legendary with a nice set of wheels and a ride height adjustment. The opposite can happen when you have a nicely restored vehicle that has dirty, beat-up, or badly finished wheels. It can ruin the overall appearance of the car or truck. We're here to show you how to make your rolling stock look as good as your ride with these 10 tips to powder coated wheel perfection.

      1. Preparation Is Key!- Powder Coating, like traditional paint, requires a clean, dry surface for the best results. We suggest to media blast your wheels down to bare metal for the best powder adhesion. Powder coating is a "high-build" coating that will fill the texture left by media blasting. Eastwood offers DIY Media Blasting Kits that make it a pretty affordable option. The other option is to remove the finish chemically or mechanically. Both methods can be quite messy and time consuming, but they do the job. Once the wheels are free of any old coatings, wash them down with a solvent like PRE or After Blast to remove any grease, dirt, or grime. At this point we'd suggest wearing clean rubber gloves. The oil from your skin can transfer to the surface and actually cause imperfections in the powder during curing. Remember, the cleaner the better!

      2. Pre-Bake Wheels- The wheels on your vehicle are subjected to some of the harshest conditions on your vehicle. They see extreme temps, brake dust, grease, grime, salt, and anything in between. No matter how often you cleaned the wheels (especially cast wheels), they'll still have some residue or contaminants baked into the metal. Those contaminants can release when the wheel is heated up. If that happens when baking and curing your powder, it could cause popping, bubbling, or even a fisheye effect in your cured powder. We suggest to bake your wheels at 350-400 degrees for 30 minutes to an hour to assure that you have released and baked out the years of contaminants in the metal. This way when you apply the powder and cure it at a similar temperature, those contaminants would have already been released.

      3. Assure you have a good ground connection- Grounding your wheels to the powder coating gun is very important. Most wheels have some tight corners and crevices that can be difficult to get the powder into. The static charge that is created by grounding the wheels and charging the powder is what helps the powder cling into every crevice. Without a good ground the powder won't stick in these spots and you'll get an uneven finish. We've had luck by running thin metal wire around or through each wheel and then connecting the ground to the metal rack the wheels sit on for coating and curing. This allows you an easy spot to clamp your ground clamp to the rack or even the wire under the rack.

      4. Hot-Flock you wheels- "Hot-Flocking' is a procedure where you preheat the part and immediately coat the wheel. The hot wheel will help the powder "stick" to the surface easier as the powder may begin to melt as soon as it hits the surface. This technique takes some practice to perfect. You will need to be quick with laying the powder down so the part doesn't cool too much. Also be mindful to avoid laying too much powder during this method as you can get "runs" or "clumps" of powder that will collect in one spot.

      5. Use High Temperature Masking Tape- Use this high temp tape to mask off lug holes, hub bores, and any other areas that have a tight tolerance and could cause issues when refitting the wheels. You can also use this tape to mask off portions of the wheels to apply a second coat of powder for a custom application.

      6. Apply Clear Coat Powder- Use your choice of clear powder to add an extra layer of protection to your wheels and make cleaning brake dust and road grime off easier (high metallic and textured powders especially hold dirt and grime!). Additionally our high gloss clear powders really give your finish a "deep" "wet" look.

      7. Protect the inside of the wheels- One of the nice things about powder coating is that it helps seals the metal and keep your wheels from corroding. We have found a good practice while powder coating your wheels is to apply a layer of powder on the inside barrels of the wheels to protect them from corrosion. The inner barrels or hoop see the harshest conditions. You can make the coating as basic as satin black powder or go full custom and use an eye catching Translucent or Candy Powder.

      8.Remove anything that shouldn't be coated- If you don't want it coated or it can't handle the heat, you must remove it before starting the process. This includes valve stems, sealing rings, trim pieces, lug covers, hubcaps or center caps, etc.

      9. Use metal or high temperature filler on damaged wheels- Have a wheel with some "curbing" or damage? Use an all metal filler like Lab-Metal to fill and sand imperfections smooth. Powder Coating can have some filling properties, but heavy scratches or gouges need to be filled. Alternatively you could use an AC/DC Tig Welder to weld and fill major damage.

      10. Use a Quality Powder Gun- As mentioned earlier, powder coating wheels can be difficult with all of the crevices and tight areas you need to coat. Not all powder coating guns are created equal and you need to make sure you use a gun that has the ability to switch to a lower voltage that allows the powder to cling to those hard to reach areas. Our Dual Voltage Powder Coating Gun is one example of an adjustable voltage gun.

      If you follow these tips and take your time, you can make your wheels look as good as the rest of your ride and last just as long too!

    • Make it Fit- Building and Modifying a Custom Aluminum Radiator With the TIG 200

      In the world of building modified cars, you have to be willing to think outside the box to make different parts jive when building a car. Whether it's notching the frame to lower a vehicle, rolling the fenders to fit oversized wheels/tires, or fitting an upgraded radiator to cool that larger engine you stuffed under the hood, you have to be ready to modify and customize things to make it all work correctly.

      This is the case especially when building small cars with larger or higher horsepower engines, where space is at a premium. I've always come up against issues finding a radiator that was just the right size that fits nicely, and cools the car better than the stock radiator did. There are a lot of large aluminum radiators for sale out there on Ebay and other sites to fit street rods and muscle cars, but the smaller ones to fit the space I needed are slim to none. Even the ones that are close to the right size, usually don't have the outlets in the correct place. Luckily we had a couple large aluminum radiators suited for small block Chevy V8's laying around and after eyeballing them, I decided to try cutting them up and building a radiator to suit my needs. It's only metal right?!

      I started by cutting the end tanks off the core at the welds, Once these were off I could cut the core down to the height I needed. The core is basically (in this case) made up of rows of thin aluminum tubing that are connected by fine metal fins and then housed at each end by base plates. Once I broke it down to the basics like this, it was pretty easy to see what needed to be done to cut the core down to a more suitable height for the Volkswagens I was building. I first marked and cut the base plates on each end between two coils (the thin metal tubing that the coolant flows through). This got me to the height I needed, and I then began cutting and sectioning the end tanks to the size I needed and moved the outlets to where I needed them. Some sort of tape here comes in handy and helps hold it all together to give you an idea of what it will look like and even allows you to do an initial test fit. Remember it's a lot easier to change the radiator layout when it's held together with tape rather than weld!

      With everything taped up it all seems a lot more doable.. just weld each seam up, pressure test, and mount it in the car right? Well in this case.. not exactly. By moving both outlets over to the same side, I needed to convert it to a dual pass radiator. Originally the coolant came in one port and had to travel across the radiator through the coils to the other outlet and back into the engine, but now the coolant would take the easiest path and straight down through the other outlet. So to make a "dual pass" radiator I needed to add a plate below the top inlet that blocks the water from flowing straight out the bottom port and instead through the coils, thus lowering the coolant temperatures. I cut a piece of aluminum plate to size, then sanded it with a belt disc sander until it was a tight fit with a slight bevel. I then used the Eastwood TIG 200 to weld the cap to the endtanks. Before I laid the final weld sealing the two halves of the end tank together, I took some high temp, waterproof epoxy and sealed the edges around where the plate sat near the coils. Using epoxy avoided putting any unnecessary heat into the coils and sealed the plate from leaking.

      With the radiator now converted to a dual-pass, I welded the rest of the endcaps onto the core and added my outlets and overflow port as needed. I did a basic pressure test by capping off all of the outlets, spraying the seams of the radiator with soapy water, then applying around 20psi with an air nozzle off of the compressor through the overflow outlet. Any air bubbles that popped up I cleaned and rewelded the area. With all of the leaks fixed, I was ready to install the radiator and fill the cooling system.

      The verdict is in, both radiators I built hold more coolant, dissipate the heat better, and overall keep the engine temperatures lower, giving me a huge piece of mind when cruising during the summer. The cost of a custom one-off radiator to fit my exact needs would have cost me close to what a new TIG 200 retails for, so once again tackling a project like this helped me save money and get some more time under the helmet with the TIG 200.
