Also, I'm not sure, but I think that if you are thinking of applying several coats, (to avoid the runs, so to speak), it's probably better to use ordinary gelcoat with a tiny bit of pigment in it and ONLY use "Flowcoat" for the last coat. This is because (as has been said), Flowcoat is gelcoat with wax in styrene added. As it sets, the wax rises to the surface and excludes the air - allowing the surface to dry properly rather than remain tacky. I don't know whether trying to put a second coat over the flowcoat (which will then have a waxy surface) would work terribly well, but I've not tried it! END QUOTE.
It's OK to apply extra coats provided the original coat has not fully cured, even then a wash with Acetone and a light sand will ensure no problems.
