Nobody that knows anything uses a grinder to polish gelcoat. Use a
real electric polisher. It spins at the right speed and won't ruin
gelcoat or burn wax. Jeeeezzzze what an idiot.


I've been working with more than 15 yards over the last 4 years and
they all use grinders. An electric polisher is a toy for cars and even
the heavy duty models are too slow for a business that's trying to
detail a dozen boats per day. Try calling Consolidated shipyard and see
what they use.
Loco, you really don't know much about the business of boats.
