Can someone point me to what products and procedures would be best to use in this case? Maybe an existing post… It is the corner of my 20year BMW door (drain hole issue). I have 3 corners to do. With the paint bubbles the worst corner is 3″x2″.
Also, I was thinking of pulling the black plastic piece off of the door bottoms and cleaning it. Is there a product that I should consider coating the area with before reinstalling the black piece.
