This time I made up canvas filler using the first recipe in the Knowledgebase. The paint base was Sherwin-Williams industrial enamel, which I had read in other posts had been used and worked for other restorers. After application of filler in the basement workshop during the winter, the canoe was hung from the floor joists where it stayed at 50 degrees or a bit higher, and low humidity, for over 3 months. Touching it occasionally, it seemed hard, but I took it down and went at it with a sanding block. Although it is 90% hard, I am finding numerous little 'sticky spots' where to outside millimeter comes off, as if it had skinned over and then did not dry completely underneath. I'm not ready to give up yet, and with summer coming, I'll set the canoe in full sun on some 90 degree days and hope that bakes it to hardness. But this sure slows the restoration process. Have others had this problem and do you have a better solution? Thanks for the help, Tom McCloud
