Bought two colors black and gray so can paint two colors to get solid coats in between with no misses. Three coats total on my utility trailer.

Self Etching
I was looking for a good self etching aluminum primer. This primer works very well and it sprays on really good. It has excellent adhesion.

I had been using SEM. This appears to have more ingredients than the SEM product. So additional stirring is required!~P.
