Right now I’m a bit annoyed with Rust-Oleum paints! I cannot find semi-gloss black spray paint in either the 1) Engine Enamel 500F or the 2) Professional High Performance Enamel. Plus, I’ve never even seen the 3) engine enamel 500F primer. I started an engine compartment restoration on my 37 coupe using 500 degree semi-gloss engine enamel and needed to continue with semi gloss. I chose the 500F degree paint as an added temperature protection above their normal temperature paint which I believe is around 200F degrees. After running out of the 500 degree paint I cannot the Black Semi-Gloss anywhere locally. My next choice was their Professional High Performance Enamel semi gloss black spray paint and it too cannot be found. What other Semi Gloss Black paint would be recommended?
