I'm doing a spot repair on a boat and I was wondering about gelcoat. What I've read about it is that you spray on 20-30 mils thick.
So, is it even ok to spot in gelcoat or blend? What tip size?
Could I use a roller?
Any differences I should know? Is it more expensive?
btw, this is on the top of the boat so should I just use a white automotive paint and blend?
