  • Protect the Underside of your Off-Road Vehicle- The Coatings you need.

    Keeping the underside of your car protected is more important than you may think; even on your daily driver. Most "rotted out" vehicles you see started rusting in the underbelly of the car or truck. These are the areas that weren't protected properly from the factory or had a poor coating that broke down from year-round driving. On 4x4 and Off-Road vehicles the risk of road salt isn't as bad as the damage caused by driving over "stuff" (that's the fun of it right?). Your factory coatings aren't going to hold up to the rock chips, brush, etc dragging under your vehicle. The truth is, no coating can withstand some of the extreme conditions seen when rock crawling or off-roading. Think about it, if it damages the metal, NO coating is going to be able to withstand that sort of impact. But there are some coatings, or combinations of coatings that can hold up better than others. I put together a list of a few of my favorites below.
  • Rust Converter vs. Rust Encapsulator

    Let’s face it, we all have rust issues to deal with. Some projects are better than others, but it’s hard to find a project car or truck that has no rust at all, even if it comes out of the Arizona desert. Eastwood makes many products for dealing with different rust issues. Two of the best and most used products we offer are the Rust Converter and the Rust Encapsulator line of products.

    These products are both very different in their uses and application, but they both have the same purpose: to stop rust from ruining your project. Sure, in a perfect world we would all start with having the individual components of our project car acid dipped and media blasted down to the bare metal again. But, none of us live in a perfect world. The best we can do in most cases is get the car clean and dry, though still rusty, and proceed with chemical solutions.

    Rust Converter in Progress

    Eastwood Rust Converter is typically applied to the rust you just can’t remove. It works best with rust that is worse than just a surface discoloration. Rust Converter needs the rust to work; it’s like a 2 part system with the rust acting as the activator. If you were to apply the converter to bare metal it would have barely any affect, and would not cure properly. When applied over actual rust it reacts with it, converting it into a hard black polymeric paintable material. The converter however is not UV stable, and is not meant to be a top coat, it’s more like a paintable primer. You can use nearly any primer or paint over the top of rust after applying the Rust Converter. The best thing to apply though, to really guard against rust coming back, is the Eastwood Rust Encapsulator.

    Rust Encapsulator

    Rust Encapsulator can be applied over lightly rusted metal, or even clean bare metal, and seals it from moisture and corrosion. Plus, any rust still under it is encapsulated and stopped from spreading. For use around the shop, house or farm you can spray it directly and not even bother with a top coat of paint. Because of this Eastwood offers it in a variety of popular colors like red, white, grey, silver, black and safety yellow, as well as a clear coat.

    For restoring the underside, chassis and underhood areas or your project, we offer it in a regular black, and an even tougher rubberized Encapsulator Rubberized Rust Encapsulatorversion. The encapsulator flows into hard to reach spots, penetrates deep into the rust, and even fills in minor pinholes and surface imperfections. It’s so tough you can apply it to rusted body work, then apply body filler over top of it and still get full adhesion. The Rust Encapsulator should be the last step in your rust neutralization/removal work before starting with primer, paint and the rest of the finishing process.

    So there is the four-step process for fighting rust: 1) Chemical and mechanical stripping to remove the rust 2) Rust Converter to neutralize and convert the rust into a paintable surface 3) Rust Encapsulator to surround and seal any rust that is left and keep it from coming back 4) Prime and paint for long lasting rust proof and cosmetic purposes.

    Do all this and your car should look good for many years to come, even through New England winters.

  • Rubberized Undercoating and Rust Fighting Paint Combined- Eastwood Rubberized Rust Encapsulator

    Eastwood Rubberized Rust Encapsulator

    We love getting product requests from our customers. The Eastwood tech department gets hundreds of requests, ideas, and suggestions a week as each of you tackle your projects. Two of our best selling products are our Eastwood Rubberized Undercoating and Rust Encapsulator, but many of you (myself included) are on a time crunch, and the time it takes to apply (and cure) two separate products can be tedious. After an overwhelming request from our customers we decided to combine these two products into a one-step process, our new Eastwood Rubberized Rust Encapsulator. Now you can fight rust with our popular Encapsulator formula while you reapply undercoating on your vehicle. Best of all you can spray this new Encapsulator directly over rust, while basic undercoating requires you prep the surface and rid it of any rust before applying.

    While we were designing this new one-step product we didn't just mix the two vats of product together like you may think, we took the time to test and perfect the formula to assure you get the best of both worlds. We salt spray tested this new formula for over 500 hours to assure it will stand the test of time. To compare, most "exceptional" paints and coatings have a 200-250 hour salt spray duration, and low end paints and coatings are 100-150 hours. This alone makes it a no-brainer to use on your next project!

    As always send us your ideas for new products and improvements on our current product line, we DO listen!


  • Rust Insurance, every car needs it!

    Why do you need it? Because rust usually starts where you can't see it, working from the inside out. With changes in temperature and humidity, condensation forms on the often unprotected inner body cavities. The most rust prone areas are usually in the lower sections of the vehicle. Rocker panels, lower fenders, inside doors, and other areas from an imaginary line drawn slightly above the wheel arches down.

    What can you do? Not many of us are able to keep our cars in a perfect climate. So the only practical alternative is to seal those rust prone inner surfaces. The problem of course is two fold: How do you properly prep? And, How do you reach all those inside panels?

    Prep is not a problem because Eastwood Heavy Duty AntiRust Aerosol (16018Z) and Heavy Duty Anti Rust Quart (16017ZP) is designed to use capillary action to displace moisture and penetrate through existing rust to prevent further moisture and air from reaching the surface. Eastwood Heavy Duty AntiRust is a waxey oily product that eventually dries as hard as candle wax. This product also works well to lubricate internal window mechanisms, and leaf springs. There's a short extension wand on the aerosol version but how can you treat a long section of rocker panel or door?

    The Undercoating System (16003) is suitable for applying quarts of Heavy Duty Antirust or most undercoatings including Eastwood Rubberized Undercoating. The Undercoating System includes a 30" flexible wand, 20" rigid wand, 5" closed quarters wand, plastic bottle, pressure head and gun assembly, 45 deg. reverse spray tip, 90 deg. directional spray tip, and a blast tip. This Undercoating System Gun works best at 90-120 psi (requires 5-6 cfm). The various extension wands can usually be inserted into existing openings, or where no holes exist a 1/2" hole can be drilled. The Unibit Drill Bit For Undercoating Plugs (16003B) is a single flute shallow stepped drill that's perfect for drilling a perfectly round hole near a backing panel. After the treatment the hole is easily "capped" with an Undercoating Plugs 1/2 Inch Plastic Pack of 25 (16004).

    Be Sure to clear all drain holes located along the bottom edges of most rocker panels and doors and provide some means to collect the surplus Heavy Duty AntiRust that drips out. This surplus can usually be strained and reused.

    For those inner fender areas the Eastwood Rubberized Undercoating available in Aerosol (16007Z) and Rubberized Undercoating 830ml-28 oz Quarts (16008ZP) provides a nicely textured satin black barrier against stone chips. It's paintable too! So you can match the body color if desired.
