More questions to the gathered expertise. What is the time limit if i want to do an chemical bond between filler coats? How quickly does this amine blush appear? (Not fast curing) If sanding through the glass there isn't much to do is there? (yes thumbnail sized area high upon the bow) I've been reading that it is the length of the fibre that is essential for strength so patching that area isn't going to help, or am i wrong here? How much epoxy is used to do a filler coat? Should the cloth be totally filled with the first filler coat? If I want to sand some areas epoxy runs etc. should this be done last before putting the varnish on or should i put an thin coat of epoxy over the sanded hull-deck before varnishing? Nick, a search engine to the new old message archive would be greatly appreciated.
