After removing my windshield I found allot of surface rust. I used a 3m “rust remover” wheel on my drill and then soaked the frame in naval jelly. Now I have have clean but pitted metal. What should I do next? I have allot of supplies to work with. I have some ppg epoxy primer, por-15, por patch, and some rattle cans of eastwood’s rust Encapsulator. I was thinking of using the epoxy primer, then the por patch to fill the pits, and then top coating with another coat of epoxy primer. Is this the right procedure or should I try the por 15 paint?
