Fortunately, I haven't had the phone ring while I've been dispensing resin & hardener, but I have had it ring while applying it... my phone in my basement work area is pretty well coated with epoxy by now...dialing out is problematic, since the "3" is now sealed tight. My friends routinely ask if "I'm in the middle of something" if they hear the radio in the background, and graciously call back later. If it's a non-distraught sounding parishioner, I quickly explain that I've just mixed up epoxy and ask if I can call back in about 10 minutes... and if it's someone I don't especially want to talk with (like the manic-depressive woman who was calling me repeatedly--- at home, at night, on my day off, early in the morning, etc.) I say I can't talk and suggest that the person call me in my office during working hours. If it's a phone solicter, I just hang up.

I use the alternate "pump resin then hardener" method... If the phone were to ring while I was actually dispensing, I'd take a moment to make the squirts "even" -- *before* answering.... better to work with a smaller batch (and then mix up more) than to work with an imbalance between resin and hardener!

And-- when in doubt, I'd throw it out!
