I have some questions about painting a shop. I have a 40' x 60' shop and I am going to paint the legs. THe legs stick through where the tin is. It is also a metal frame building. I was told to use dplf epoxy primer to seal the legs. Right know i am soda blasting the legs and getting ready to paint. I was wondering if anyone had any other ideas on what to lay on for a primer and which line of paint. I am thinking of a single stage over the primer. I want some opinions because I am new to painting and i am just going by what a body shop man told me.
