Thought you guys might get a kick out of this. The underside of the hood on the Ferrari kit I'm werking on had a few knots in it. I start sanding away expecting to hit either an air pocket in the glass or just a mound of resin. WELL what I find is indeed a pocket in the glass. but what is IN the pocket is the kicker. It appears to be f-in tile mastic ! You can even see the trowel marks in it !! If anyone on the fiberglass business can tell me what this is all about I'd LOVE to know

if that was a vacumned mold i would bet they cut the vac early. it looks like foamed epoxy pulling thru the glass into the pocket but did not let it sit long enough to suck the pockets closed.

It's closed cell pour foam. I have used it extensively in body panels and props. Primary use is in the boat hull industry for Coast Guard floatation requirements. It allows thinner mat layups and thickens the panel over straight mat and resin also enhancing rigidity. It does require a tool to spread it out in large surface areas so a trowel used wouldn't surprise me. If the non exterior surface is a little wavey it is PF.
