I'm thinking I'm going to use POR 15 down inside all the frame rails to go over that rust and such. Then when the new floors are welded in the insides of the frame rails would be coated.Riddler
I'd give them a quick buzz with a flap wheel and then POR 15 them. While the POR15 is still tacky, I'd hit it with primer and then finally some colour. That way when everyone is ooooohing and awwwwwwwwwwing over your ride, you can point out the colour inside your framerails...... well if they look real hard through some of the factory holes.
Geez man, you're slipping! Details, DETAILS!!!!! :toothy10: Besides, what else are you going to do with your time? :snakeman:
