Just started the body work on my new project and I am having trouble deciding what primer to buy. I have done the floor pans and will be doing some more patch panels along with some more paint removal/body work in the near future. I need to know if it would be best to go with your epoxy or urethane primer to coat the repaired areas with? They are for the most part bare metal and I will have to use filler in some spots too. The truck is being kept in the garage and will not be out in the weather till its done, i just don’t want to leave the bare metal exposed to moisture. Is the urethane ok to put on bare metal and be painted over, or will I need to seal it with epoxy primer?
