don't worry about them mostly unless you're getting one every few inches,,how about putting a light bulb and bug trap upwind 50'? They sand off. The bigger issue will be varnishing bugs. Don't know chinch. 45 degrees is a bad idea. 60 is fine,,55 is close to 60 but it's also clost to 65 which is better than 55,,,don't sweat it. If you have extremes of temperatures then presealing wood is a good idea before glassing. I think the general formula is halving or doubling of cure times every 15degree change from room temp,,that's rough estimate. I think theoretical strength is affected by cure temps but probably doesn't make a big difference,,the epoxy is still harder than the wood. It's not possible to give cure times without knowing the epoxy,,,also remember that in a 24hr period if the temps dip down into the 50's and into the 70's you aren't getting 24hrs of 60degrees.

: Is there anything I can place on curing epoxied surfaces to prevent bugs from
: becoming embedded in them or making bugtracks? Wax paper?

: My workspace is prone to large explosions of fly and lacewing populations
: after the weather turns warm for a day or two. Cold weather kills them
: (time for the vacuum cleaner...) but then they return after another warm
: respite. I haven't found where they enter from, though it may have to do
: with the skunk that I think lives under the room. Chinch beetles also
: "visit." Which brings me to another question: do chinch beetles
: chomp on wood? Okuome plywood, to be specific?

: How long does the epoxy take to cure in, say, 55 degrees, 65 degrees, and 75
: degrees, assuming low relative humidity? Would 45 degrees be a bad idea?
: The reason I ask is that although I will do the epoxy work in the daytime
: to take advantage of the greenhouse effect, nighttime temps drop
: drastically in this dry climate. Yes, I can put in some lightbulbs for
: warming, and I plan on keeping a portable oil-filled electric radiator
: handy. There is also a little heat coming from the adjacent studio, which
: has a forced-hot-air heater. I just wanted to know what the temperature
: limits for a strong cure were.

: Thanks for any help with this.
