This is the way to go for metal prep before using paint. It takes two to three coats to cover bare aluminum with this thin green tinged primer. This primer is very thin-bodied and needs to be applied in VERY LIGHT coats. The first coat will appear blotchy and irregular, that's fine. This is used to get good adhesion to difficult to paint materials such as aluminum. This is an excellent primer, especially for use on aluminum which is usually very difficult to paint, but the method of application is NOT like other primers.
Why We Like This:
Wets out great, does not run, dries to a nice flat olive green color
Excellent self-etch primer, especially for aluminum
