Not that hot where I live now, there's still a bit of snow from that storm that whacked Texas That was an extra cold storm, but we usually have snow here for a few days after a storm passes through. Rarely hits 100 in the summer.

Most of the work like this I did when I was in Tucson, they used to put the 2 hour epoxy out in the sun in the summer - cured in about 15 minutes! That may have contributed to the bubble problems, I've seen it smoke pretty good on a summer day.

I rarely did that myself, but the shop had a kid that did the filling and milling for the assemblers so you couldn't always control what you got to work with. A bunch of us would do our own milling if the boss wasn't around to give us dirty looks
