Looking for advice on how to repair hole in shower wall

Hi everyone,

I just bought a 2001 Newmar Mountain Aire 3763 on the Spartan chassis. It's in good shape, a few small things to do here and there, including this hole in the shower insert. I'm not too worried about moisture getting behind the insert, because it's all the way at the top, but I would like to fix it.

I'm new to RVs and have never made a repair of this nature - what's the best way to fix this? Picture attached - thanks in advance.

If it's fiberglass, I'd push tape or a piece of aluminum flashing in behind the hole to form a backing. Then use Bondo body filler to fill the hole. After it dries, sand flush and paint to match.

That looks like the lower skylight cover to me. If so, you can buy that entire piece and just replace it to look like new. You may want to replace the entire skylight while you're at it if it is original to the coach.

Replace but in short time repair can be easy.

Check if plastic by scraping off a sample.

If it is then sprinkler pipe glue will bond great and fast.

If fiberglass then epoxy is needed.

If plastic visit a hobby store where plastic models are in abundance or a plastic supply house.

They sell small sheets of real thin plastic for making miniature buildings and other items and a patch can be formed and glued.

Cottage cheese containers also work great for this too.

Heat and form patch to shape then glue it in and after complete paint it to be close and it will not bee noticeable and not leak.

Call it a "dofur" (do for now)

just a side note.. marine glue/caulk is some amazing stuff!

This stuff is completely water tight and not removable. But it won't fill that big of a gap on it's own. but if you had some sort of cover, this stuff would never let water by it.
