Hi David,
ProtectaClear Coating is the coating for your motor parts. ProtectaClear is an easy to apply, one part clear protective coating that will seal and protect metal from sun, salt air, oxidation, corrosion, moisture, tarnish and other damaging elements. The amount of time it lasts depends upon the use and abuse that it gets
If you polished or cleaned with any acid based products, the surface will have to be neutralized before coating.
ProtectaClear is tough and durable and is practically invisible on polished metal. The coating is stable up to 500 degrees, and will gas off at 660 deg F. We have many car enthusiasts that use ProtectaClear on their cars, not only on engine and engine parts, but also on their trim and rims.
The metal to be protected will need to be completely clean and solvent wiped with either denatured alcohol, acetone or xylene before applying the coating. The solvent wipe will insure that the coating will adhere properly. Then, ProtectaClear can be applied by spraying, brushing or wiping it onto the surface. ProtectaClear is self leveling so any brush or wipe marks will level out when left alone to dry.
ProtectaClear will not chip, crack or peel and will never discolor, darken or yellow.
We will be happy to help you figure out what you would need for your project. ProtectaClear can be purchased by itself or in Kits with polishes and cleaners securely on our website or by calling our office at 800-304-0566 or +916-852-0200.
Please contact us if you have any additional questions. I am looking forward to hearing from you.
Thanks again for your interest.
