Re: How do I keep my hood from doing this after its painted???

If a metal prep such as ospho, etc was used and not neutralized properly, the excess acid could cause a reaction under either epoxy or filler (if either was applied directly over the treated metal) and result in delamination. Whatever the cause, it renders the rest of such repairs suspect. Something to rectify before the expensive part (paint) goes on...
