Rustoleum Fiberglass Paint

[barmcd]

I’m going to repaint the center textured section of my roof with Rustoleum fiberglass paint. I’m trying to figure out if one gallon is enough for a 40’ coach.

Looks like 100 sqf per qt.with 15%loss in spraying or roller loading.

Thanks, looks like 1 gallon should do it.

Dennis,

I painted our fiberglass roof with the Rustoleum Topside for boats and it took two quarts.

Here's a link to the technical specs. If you look at page 3, you'll see that 1 quart covers 100 sq ft.

Ours is a tick under 39" feet and it took 1.5 gallons (Topside) to do three coats. I taped off the sides and painted all the way to the edge. I also painted farther out to the front and back past where the caps are incorporated since they were faded pretty bad and no one would be able to see from the ground. I found that pouring to much paint in the paint tray was bad as the paint started getting thick towards the end when the tray was starting to become empty. Scotchbrite sanding and cleaning took the most time. I ended up using a small palm sander but with the Scothbrite pad. It was not a master piece by no means but it came out ok.

Here is a write-up from the Beaver Ambassador Club on using the Topside paint.

Thanks. I've got a few cables on top of the roof for a XM radio, CB radio and satellite TV antenna. Remarkably, they aren't attached with any of the usual cable ties, but are held down with liberal doses of dicor unless they are under there. I planned to remove the dicor and install cable ties, the reapply the dicor. That write up makes me reconsider that since removing dicor is a royal pain.

Reading up on this, the rustoleum paint is oil base, dicor fiberglass paint is an acrylic resin. Wondering what the advantages/disadvantages would be for those formulations. Seems the acrylic would be more suitable for fiberglass but anything made for marine is usually pretty tough.
