Stripping gelcoat

Hey all. Been a while! The Ventura is coming along great with the interior 95% complete. Iíll post some pics in another thread a little later.

My current question is about fiberglass/gelcoat. The roof of the camper is quite badly damaged and my plan is to strip the gelcoat off and add several new layers of glass. Sounds like a good idea...the only problem is that stripping the gelcoat off is proving to be a nightmare. Any tips for removal? Can I simply lay new fiberglass over the gelcoat?

Your help would be greatly appreciated! Oh and if you have some warmer weather feel free to send it my way, Iím currently sanding on the driveway in -16C!

Generally, glass should be laid on glass unless you're talking about a small repair where the edges are still gelcoat. Put it on gelcoat and you'll probably be able to pry it up with a putty knife. Removing gelcoat is difficult to say the least. If you take a look around the fiberglass boat forums you'll find that the usual method involves very aggressive sanding (no finer than 40 grit) and a lot of time and patience. Once down to good glass, you'll have good adhesion for additional layers.

I don't know why not. That's exactly how repairs are done. I don't know of anyone that completely removed the gelcoat to do a repair. Yes it needs to be roughed up and completely wax free before the repair is started.

Good luck. Post pics!!

6" angle grinder with 40 grit disks, wear a breather mask as you'll be making a lot of nasty dust.

Mostly hail damage. And lots of pin holes. 5 or so bigger cracks from who knows what! I pulled it out of a farmers field so itís anyoneís guess.
