I am painting fibreglass and ive been told i need to use a flexible undercoat, what is the best way product to use?

On my panels (gel coat and sand blasted steel) we used a 2K acid etch primer, then a high build 2k primer, 800 flat, prime, flat etc and then top coat.


Check with your paint supplier that it is OK for polyester gel coat.
