Anyone ever used a Preval Sprayer for spraying gelcoat? My one friend said they don't work very well, but he's a professional fiberglass repairman so he's used to using high end equipment. I just have a few small areas of deck that I'm putting back together and can't really justify buying a compressor and spraying equipment. So my other options are to try to brush on gelcoat or see if my buddy can spray it for me.

Same question regarding Gibco Flex-Mold for repairing non-skid - anyone have experience with this? It's kind of pricey at $54 for a 1' x 1' square but looks like it could be the best option for matching the original non-skid texture on the deck.
