I tried some of the white glue mixture on a piece of foam today, after a day or so drying. Straight nitro dissolved right through into the blue foam that I used. I guess it isn't really fuelproof. It was a fairly good finish, and applied easily. I guess I wouldn't be using 100% nitro. I am trying to get a new method for painting too, now that no VOC paint is the norm. I'll keep searching, and trying with the glue thing. I found some clear glue that smells a bit like the white glue to try.
