tunnel paint.

I could use some help choosing the best paint for the metal walls in my tunnel.
I've tried macropoxy and it did not last and turned yellow. The walls were preped correctly and it was given a week to dry but it did not last.

Try attaching smooth, gel-coated FRP panels to them instead of painting. Painting walls in a car wash is a fools errand.

Couldn't have said it better myself...been there, done that.
