I'm looking to put a patch in the battery tray on my VW camper where it's corroded right through. I could replace the whole tray but I'm trying to not damage the external paint. I've got 2-3 cm of good metal where tray is welded to the outside of the body.
Is there a way I can keep the body cool and not burn the paint?
