Fiberglass prep for Monstaliner

[furnJim]

Considering that Monstaliner is textured I am wondering how good the prep on the fiberglass needs to be? My only previous experience was in building a cedar strip canoe that I finished with spar varnish and I am thinking that I can get away with something less than that level of prep in this case.

I would agree.

I would also recommend using their primer. I have a couple of chips in mine and Tom & Shelly used their primer and there's is clean without a diamond plate front.

Just wash off your amine blush BEFORE you start sanding.

Tony, in your book you recommend a Rustoleum product as a primer, which i have already purchased, by the way. That's my next step. Would you recomend switching at this point?

I would. I think you'll get a much better bond. Chemical instead of physical.

Already ordered it. Didn't seem worth taking a chance.

We actually used Rustoleum Marine Coatings Primer (per Tony's recommendation? I thought we did it because you used it Tony.) Anyway, it adhered well to the epoxy even though we forgot about the possibility of amine blush. (Do wash it first, we got away with something, maybe because of our dry climate, or maybe because the Raka epoxy we used is supposed to be blush free. But washing is so easy, it should be done to be sure!)

I looked at our tear this morning and we do have a few rock chips under our front cargo door. So nothing is perfect. Not sure what Monstaliner recommends, but make sure it will adhere to your fiberglass/epoxy surface.

Oh! Your finish sure came out nicely.

Thank you!

The Rustoleum Marine Coatings primer (roll-on) seems to be pretty good stuff. Not so, btw, one of their spray on primers that should be compatible with their paints, but isn't. We used it on the floors and on the slab of plywood I put on the front to mount the propane tank. It adheres well to the epoxy, but not to their hammer finish spray paints or their sand finish floor paint. The propane tank mount has all sorts of rock chip damage, evidently down to the primer.
