I am making new cabinet doors in my 13' and expanding a couple of the closets in the process. The doors and storage areas in that narrow cabinet next to the bed are taller in the new models. I'm doing something similar. Because the doors are taller, I'll need to relocate at least two of the hinges. That will leave screw holes in the fiberglass. Is there a way to fill those to match the existing fiberglass, or at least come close? I know very little about working with fiberglass. Suggestions and comments would be very much appreciated.

Patching closet screw holes
Patching satisfactorily with fiberglass would be very difficult. I suggest plugging the holes with rivets (white ones are available). Simple fix (I have done this.)
Thanks for that suggestion. I've looked at some videos about patching fiberglass and it is quite a process for just these little holes. Since I'm making the cabinets larger, ie, cutting a larger opening, I've thought adding a stiffener inside along the sides might be a good idea. I could use the rivets (or small flat disk machine bolts) to attach a wood or metal strip. Thanks for the idea.
I've just used caulk to fill the holes. Hardly noticeable.
Thanks. I'll try that. I find many things are so evident while one is working on them and then quickly fade from view once the project is done.
Late to the party, but I recommend using a two part epoxy product called Marine-Tex in white. It results in a very strong bond with fiberglass and has the same appearance. It can also be sanded and painted if needed. I've used it to make repairs on my Scamp as well as on fiberglass boats.
Thanks for the suggestion. After watching boat repair videos, I thought this could be a good solution, especially since these are small screw holes. I tried some caulk but would like something that blends better.
I did purchase a different brand - Nanoxa - of the white epoxy (same mixing) but haven't tried it yet. I wonder if it's any different from what you've been using.
Thanks again for the suggestion.
