: Thanks for the feedback. I have to say that I absolutely cringe at the idea
: of chemically removing all the partially set crap.

: TAP uses a 4:1 ratio on their marine epoxy. In fairness, the epoxy sat around
: for a couple of years and was subjected to temperature extremes of roughly
: 32 to 90 degrees F. Still, I've never had a lick of trouble with West
: systems. It's also entirely bogus that TAP didn't list the 77 degree spec
: on their cans.

i have some Tap epoxy that has sat around for a couple of years in my garage and still use it to glue up things with no problem.I do use a scale to measure things out though, at 4 - 1 ratio i find the hardner pump spits out to much
I have the medium hardner and really pay no attention to temps when mixing or applying. It does have a blush when cured,but that washes off easily. That being said I still prefer system three epoxy, no blush, and you can
recoat in 3 days or less with no sanding (chemical bond)
