Alright i have a old Chest freezer that im turning into my home brewing fermentor. It has some small rusting and places where the paint has chipped away. I know that i can go buy appliance paint and paint over the spots. But wanted to know if anyone recomends a adhesive or something to put down as a base coat to help this from not happening again. Any prouduct that anyone has used to repair rust spots on a freezer before applying paint would be much appreciated! Thanks in advance
