: I did the pvc tarp tent and will never do that again. It was horrible. messy
: and could not get the heat all the way around just created more problmes

I've been "micro-tenting" the boat outside in my hoophouse, and can't get even heat distribution either. So far I've used the tent deal to fillet and tape the hull seams, and for the scarf joints earlier. It gets darn hot at one end where the heat is blowing from (100*F) and maybe 60-70* at the other end of the boat. The hot end cures fast, but I've been seeing overall overnight cures and it's in the 20s-40s at night, 30s-60s in the days last couple weeks. The tent is a pain, but it's been working for me. Snowed three days ago, today was in the upper 60s with a little thunderstorm tonight! Then again, I've anticipated and been willing to put up with some aggravation to work on this boat in cold weather. Your mileage may vary. : )

What other kinds of problems did it create for you? Anything I should look out for?

On a more general note, are temperature extremes bad for curing epoxy? I have not noticed any adverse effects, and everything seems to be curing just as it did on the boat I completed last summer.
