So POR15 must be coated with some type of clear coat? Does this clear coat dry as hard as POR15? Does Hardnose need a top coat? How does it cure?
Por15 rust paint must be top coated. You must spray your top coat while the Por15 is still tacky. I never use clear coat just black paint for top coat. The top coat does bond to the por15 as one.
Hardnose does not need topcoat. Hardnose cures the same as POR15 rust paint. Hardnose is a two part paint. Moisture cured as well though.
