DTM primer

Any good epoxy primer will work for what you want. Prep the surface per the tech sheet and make sure it's clean. Use nitrile gloves and DON'T TOUCH it with your bare hands, or you will have isssues later on down the road. Another word of advice stick with one product line line PPG, DuPont, R-M, Glasurite, ect as these as designed to work as a total system. Don't start playing the mad chemist as problems can come back and bite you in the end.
