Yer liken that West Systems arent' you.
It's a good product, but it'll give the same poor results if you try to laminate FG veil cloth [5/8-3/4 oz] over raw foam. The resin soaks into the foam and the cloth is incompletely saturated in spots. The solution has been to first cover the foam with clear packing tape...use the lightest weight tape you can find.
MJD, I notice a pretty full cure within a week...the part is about as tough as it's gonna get. The gummy layer I've seen is from the foam that still clings to the FG skin after the solvent treatment.
