Eastwood Ceramic Engine Paint Application
Now it's easier than ever to detail your engine with Eastwood's innovative line of High-Temp Ceramic Engine Paints. Formulated to match the original finish in the most popular factory-correct colors, these super-durable paints can be brushed-on or spray-applied right from the can. Although metallic finishes should be sprayed for the most uniform finish, they still brush-on beautifully so you can touch-up your engine without extensive masking. The high-performance silicone resin, tested to maintain adhesion up to 650°F, is augmented with ceramic nano-particles that provide additional durability as well as resistance to chipping, marring and scratching. These paints should be mixed 4:1 with Eastwood's Urethane Paint Activator for increased gloss and chemical resistance.
Stripping Old Paint
It's a good idea to start by putting down a sheet of heavy plastic since many of the chemicals used can damage floors. It's important to read and understand the safety warnings on all labels, and work in a well-lit, well-ventilated area. Most of these products, including the paint, work best when the area and surface temperature is 65-95°F, with 50% or less humidity.
As with any coating, the surface needs to be free of grease, oil, loose rust and peeling paint. A soda blaster or pressure washer is very effective at removing most of the surface contaminants, but if you don't have one, what do you do?
To remove old paint, brush on a coat of Eastwood DeKote Paint Stripper. This paint remover is safer to use and doesn't dry out as fast as methylene chloride-based removers. Once the stripper loosens the coating, use a scraper. After the worst of the deposits have been removed, follow with a water rinse. Once the surface is dry, spray PRE Painting Prep or acetone on the surface to remove residue grease and oil.
If you prefer a more environmentally friendly approach, use Metal Wash. Mix this powdered concentrate with warm or hot water to make an effective cleaning solution that can be applied with a pump spray bottle or scrubbed on with a nail-cleaning brush or rag. Another nice thing about Metal Wash is that it leaves a protective coating behind that inhibits rust. Since it is water based, it does take longer than PRE Painting Prep or acetone to dry.
Prepping the Bare Metal
At this point you can apply the engine paint, as many of the original manufacturers do, to the bare metal. If you have rust or want better durability, you can spray Fast Etch onto the surface. This phosphoric acid-based cleaner continues to work as long as the surface stays wet. This product will etch concrete and can discolor coated surfaces, so you may want to make sure that the plastic sheeting you put down earlier is still in place and effectively protecting the floor. Keep the surface wet with Fast Etch until the metal has a uniform gray appearance. Vertical surfaces should be covered with rags or paper towels soaked in Fast Etch and pressed against the surface. You can cover the rags/towels with plastic wrap or plastic bag material to prevent evaporation.
Once the surface is a nice uniform gray, rinse and force-dry with compressed air, or spray the still-wet surface with PRE Painting Prep or acetone and allow to dry. For greater durability, or if some slight rust remains, the entire surface can be primed with Eastwood Rust Encapsulator. This will resist temperatures up to 400°F, so it's a great primer to use on an engine block. Plus, since Rust Encapsulator is available in black, silver or red, you can select a color that most closely matches the engine paint color. Selecting the right color primer will minimize the number of coats of engine paint you need to apply. Perhaps the best primer for our Ceramic Engine Paints is the 2K AeroSpray High Temp Engine Primer, which sprays 2 part paint direct out of a spray can. Thin coats of primer move better with the surface as it expands and contracts with thermal cycling, plus they're more resistant to chipping.
Applying the Engine Paint
You can apply Eastwood Engine Paints with a spray gun or a brush. Brush application minimizes the need to mask, and provides a nice finish when using a disposable foam brush like our 3-pc. set of polyfoam brushes. You may also want to spray to achieve the smoothest finish. The unique Eastwood Engine Paints can be easily sprayed with virtually any HVLP gun with a 1.2-1.5mm nozzle. The Eastwood Concours HVLP Paint Spray Gun with 1.2mm nozzle will apply this and most other solvent- and water-based paints very nicely, because it atomizes well and uses only 4 cfm at 29 psi. Reducing the paint up to 20% with Eastwood Zero-VOC Urethane Paint Reducer will provide the best flow out. Keep in mind that Eastwood Engine Paints and most other paints apply best when the area and surface temperature is 65-95°F, with 50% or less humidity. The silicone-based formulation with nano-ceramic particles offers great durability. Be sure to clean the spray gun with acetone or lacquer thinner within 2 hours of adding the activator.
