While we're on the epoxy subject I have a quick qustion. I mixed up some 10 min epoxy and thinned it with rubbing alcohol to use for applying some fiberglass tape to the inside of a fairing, it was fairly liquid for about 2 to 3 minutes then almost instantly it fired off into a hard rubber ball, so fast the second time that it actually captured my paint brush.

Question, what is the best way to thin epoxy? I have always read of using the alcohol method and number two, does the alcohol make the epoxy fire off quicker? If it does then I just need to get a longer working time epoxy. No problems with what I did just an observation and a little aggrivation having to mix it three seperate times to put on about 8" of 1" wide tape.
