Well I thought about sanding and using a scraper. I sharpened up my cabinet scraper, I have one with a slight curve and it worked great on the curves of the hull. The epoxy cured overnight and I got going before noon. The offending fibers came off real slick though I could see that letting things cure that long was a problem. Too soon and I think it would have been easy to smear instead of come off clean. The fill coat covered most of the mistakes though. I dont like the squegee that West sells to hard and real slippery to hang onto with gloves that get epoxy on. My solution was to get one of those sponge and squegee things for cleaning your car windows. 5$ and then cut it into three pieces on the band saw. Works great especially on the fill coat
and around those nasty compound curves because the rubber edge is so flexible.
