Was going to use 15 min epoxy on the centre wing bandage but the instructions mention using PVA, i can see this would sand better and maybe soak into the bandage better, anyone used PVA or are you all Epoxy users for this job?

Hi

I use Epoxy. I suspect PVA but I like the solidity of Epoxy, and a slower setting one at that.

Hi Martin,

Probably a bit late but I use PVA for wing bandages and have done so for many years without fail.

I built one of these back in the 90"s, covered in tissue and dope and sprayed with car paints and fuel proofed.

I use vanilla PVA for wing bandages. Never a problem. Much cleaner & cheaper than epoxy. I don't use thick bandages actually, I use glass surface tissue / cloth, the really lightweight stuff, and do 3 layers - one wide, one medium, and one narrow. Credit card or similar is the weapon of choice to spread PVA over the bandage. Several coats after the cloth is on will fill the weave quite well. If you use multiple layers of thin cloth it does not need blending or sanding at the edge.

Only thing to remember with PVA is the water content, so do it somewhere warm where it will dry relatively quickly.
