Most marine or for that matter, auto body shops that specialize in fiberglass or gel-coat repairs can do the job in the trailer without removal. They would just have to tape off the interior parts near the bathroom fixture and cover the rest from overspray - not that big a deal. removal of bathroom fixtures such as towel holders, soap dish, etc. would make the job more pro but the rest can be left in place. It's a good time to have fiberglass reinforcements added too if there are cracks it the old material.

Still, I have seen good results on here from members that have done it themselves. Have good ventalation and a respirator on.
