I'm attempting to clear coat a bare aluminum valve cover, but having a hard time getting it to stick. I used "Rust-Oleum Gloss Clear 600 Degrees Engine Enamel Spray Paint." It looks good when cured but it will peel/flake up with just my fingernail. Seems like it isn't sticking well enough.
The surface is completely clean, I used both a heavy duty degreaser and just before I blasted it with brake cleaner wiped and let dry. Some surfaces were sanded like the raised letters and other surfaces were wire wheeled. Others were just stripped of original paint.
Not even the raised letters will stick, and those were sanded really good.
Before I strip it and try again, what can I do to make this work? Maybe a different clear will stick better? I'm kind of concerned about heat, but is that even something to worry about? How about prep, what can I do? I'm really aiming for a raw aluminum look in some areas.
