BSI addressed this issue in our ads and on our web site:
Q When using your Super-Gold thin CA to assemble an aircraft made of a fine grain smooth white foam, there was some cratering on edges of the joints. What caused this? – L. Scribner, Southern Pines, NC
A: It sounds like the foam was reacting to the excess heat from the curing process. This is much more likely to occur with the thin Super-Gold when Insta-Set is used on it, so a minimal amount of the spray mist should be applied. Some foams, especially the fine grain blue and white foams, have much lower tolerance to heat, so only the Super-Gold+ should be used on these. Thin can be used on the fine grain foams when it is applied to the surfaces that have been cut with a hot wire. But if you were to sand an edge of that same foam, the thin seems to react with the foam dust and quickly cures, creating excess heat that can melt a lot of foam.
