Average cure time for pro-seal

Hi gang,
I know that it depends on the temperature, but what?s the average cure time for pro-seal. I?m retrofitting return line bungs in my fuel tanks, so it?ll be a very small area that I?m pro-sealing. The forecast in my area is calling for highs in the mid and upper sixties to lower seventies and lows in the low to mid forties this week.

60-70 Two or three days and it should be firm. Cure in about a week. I wouldn't put pressure in the tank for two weeks. For a small batch, I would mix it a little hotter (darker).
