Fiberglass Garage Door

[Al]

My gun club has two fiberglass garage doors. I would guess they are at least 30 years old. They get lots of sun and are really showing their age. Deterioration is on the outside and the inside is fine. I am looking for a "Restoration Product" Possibly a UV protectorate.
Thanks. So many knowledgeable folks on here!!!

You mean like a high solids paint? Acrylic latex, and an acrylic primer if you want it to last longer.

If it *needs* sanded, wear a respirator because you don't want to breathe the fibers.

The coat would "need" to be clear. Thanks

How about fiberglass resin painted on?

Hopefully demarpaint will chime in on this..

I'm thinking you'll have to stabilize the surface with a zinsser primer type product first, then topcoat.

I assume the paint needs to be clear because these are the old fiberglass doors that let some diffuse light through, right?
I'd find a good UV resistant (thinking boat/surfboard) clear resin.

You are correct. Thanks for the info.
And thanks others, so far. I appreciate it.

Im assuming that youve exhausted options for clear varnishes? Like Helmsman poly?

Id look into if a good boat paint, like awlgrip clear can just be coated without paint or primer.

Im assuming you want matte, which is also a consideration.

Everything takes me back to an eggshell type poly.

I have no experience with this, but the combination of fiberglass outdoors screams to me for some kind of marine product, like JHZR2 mentions.

I would think that a clear marine gel coat or clear coat would be perfect. And I assume, as with any painting process, the surface prep is the most important part.

Not an endorsement at all, just a couple of the first searches I came across:

Gel: https://www.fibreglast.com/product/Clear_Gel_Coat_just_gel_coats_00180/Polyester_Resins
Clear: https://www.wholesalemarine.com/toon-brite-protective-clear-coat-for-boats-35339.html

It looks like the Gel might be a little more durable, but probably not necessary for a garage door (compared to something that's used below the water line).
