Re: paint removal
Absolutey not even, that is if it was mine, Take a little time to safely remove the exisiting paint, the actual painting is child's play compared to what you are doing now. What i am saying is the work you are doing now should be as careful and detailed as you can be, it will be the foundation of your final paint job and effect it's beauty greatly.
I cant imagine how tough a paint could be to stand up to a 80 grit sand paper?
