I noticed on my stip canoe a little while back that pimples were forming in the finish. These raised lesions were brownish and felt rough. The boat was varnished with flagship on top of MAS epoxy. I varnished it outside and temp control was difficult but the varnish appeared and felt hard a couple of days later when it hit the water. These lesion seam to be spreading all over the boat and is quite ugly:( Obviously I will have to sand her down, possibly to glass but does anyone have any ideas what happened. I varnished my yak a weak latter inside the shop but otherwise application was the same. I haven't had any problems with it.
Thanks
Rick
