Any advice on products to use to clean and polish poptop without harming the
fiberglass?  Some folks have been successful with bleach but I plan on
leaving poptop on van to clean.  Whatever product I use, needs to be safe
for the paint as I bet it will run down the side of the van.

Also looks like previous owner used black sealant to hold on part of poptop
seal.  I�m going to replace seal but how do I remove old sort of glued on
sealant on the bottom edges of poptop?  Can you sandpaper or will that harm
fiberglass?
