Fiberglassing with water-based products?
What is the potential that using a water-based polycrylic for resin will warp a wing?
Also, what "recipes" are people using for thinning other heavier resins? I’m planning on fiberglassing the entire plane prior to painting, and I doubt if the heavier resins could ever be applied in a way that they don’t add too much weight. Thanks

RE: Fiberglassing with water-based products?
I use Polycrylic on sheeted structures with great result. Mixing talc on the last few coats will fill the weave nicely. I've never covered open bay wings as I'm told of a potential warping problem but some do with great success. I stick with the adheasive backed coverite for wings.
Nice not to have the Nitrate and Butyrate fumes risking life and limb but I still use Nitrate and Butyrate on the final finishes.

I have gotten warps using water based. I use 1/2 ounce glass and Deft Sanding Lacquer instead of water based. No thinning needed, it gasses off about 80% of it's weight. 50/50 blend of baby powder for the final coats. The Deft requires an open area to use, the fumes will knock you on your ear if you do it in an enclosed area!!! Other then that I get a lot better finish then with WB products.

Those warps were on a fully sheeted structure?

Is the deft laquer the same thing as a 'sanding sealer"? I like to use Minwax sanding sealer before painting becasue it makes the balsa and filler the same hardness for sanding.

I've done the minwax technique and used K&B years back. It's the epoxy paint makes the surface bullet proof. I have a plane painted in rustoleum over minwax polycrylic and it's not what I would call bullet proof.

No, not at all. It is found at Lowe's hardware with the water based products. Before you glass you do use two coats of sanding sealer on your wood then sand smooth, this just keeps the product you are going to use from soaking into the wood. With the Deft Sanding Lacquer I first do two caots of sanding sealer then sand, then I lay down my glass with one coat of Deft then add a second coat then some light sanding. It takes several coats aND i SAND BETWEEN COATS except the first one. After coat #3 I mix up a 50/50 blend of Deft and baby powder. The powder just fills in any weave you can see or feel. Most of this is just sanded off. You can tell as you go when to give it the final coat of 50/50. I also use 1/2 oz glass so there isn't a lot of weave to fill. Very easy to do. Glassing just takes more time then covering but the finished product is bullet proof. I also like Klass Kote paint but there are some very good paints on the market so search around here on RCU for that. I just like the twp part epoxy paints. Acetone won't even bother it!!
