The problem is that gelcoat, to my understanding, that is used in molds is always waxed. So yes you need to sand down to the actual glass if you want a really strong bond.
When I bought my highsider someone tried to glass over the gelcoat on the front keel, I was able to easily peel it up with a fingernail and pulled the whole thing off in one sheet.
