Thanks all, Your first comment: I called Petit over the winter to ask if I could use a single part polyurethane or a latex enamel over EZ Prime...
I will be applying an oil-based Petit EZ primer over a polyester above-waterline FG layup, then a polyurethane paint. How soon can I apply the...
If I overcoat a polyester laminating resin a day or a month later with a waxed finishing resin, will that prevent sandpaper from clogging? Won't...
How soon must PVA be applied to laminating resin before it forces a hard (non-sticky) surface? Can it be applied several weeks late? Thanks
OK. Thanks. I don't have too much experience with VE. Unless the first VE coats soak into the balsa deeper or bond better to it, there is no...
Will polyester adhere to vinylester resin? I want to apply VE to a balsa core edge to seal it, thinking it will soak in better and seal out...
No, I'm not just butt gluing it together. Grinding the 12 to 1 taper, fabric, resin, fairing compound. On top and bottom laminates. The...
Thanks all. I am looking at non-poly/epoxy resin based primer/surfacers due to the time constraints on post sanding. I want to prepare the...
I think you're talking about high build polyester resin based primer/surfacers. Like the one you referenced. I'm looking for a paint type high...
I have finished applying and sanding poly fairing compound applications to the final FG cloth surface of a crowned composite roof panel. It's...
1708 Biax/mat side 1, mat/bix/mat side2
Have done a 3 x 7' crowned composite panel (1" balsa core) using poly resin at 60 degrees. Others have said to keep it on the form as long as...
Your last point was the key. I forgot that lesson I learned 50 years ago. If there are adjacent hard and soft surfaces, they won't sand flat....
Oh OK. I'm using polyester lamination resin which will not cure hard, it will cure sticky- on purpose. You are using epoxy resin. Different
Sorry, I'm unable to explain this better. The fairing compound won't clog the paper. When I spread the filler using a fairing stick, there will...
OK. But if I put the fairing compound now on the unwaxed resin and spread it in the valleys, but no on the peaks- won't the hand sanded sandpaper...
At the final stage of building a composite balsa/FG skin panel on a male form. The last step was laminating resin with biax/mat on the balsa and...
Oh! OK. But the first layer wasn't left to get hard, only tacky. With a 1/4" "for resin" nap (not foam) roller cover, I could only get about...
OK, not the re-rollering. You don't mean 18 mils per coat do you? The 2 coats would have been about 16 mils together. Used the classic Evercoat...
Thanks. I did several multi-layer BRUSH trials on the mold. Same temps, same cat %, same approx. thickness (.008 DFT). The can says 3% max at...
