He was concerned about groceries in the box, but the only thing I
have in the one in the garage is beer.... It doesn't look like it affected
the resin at all.



Have a couple beers and I bet it will affect the resin (and the rest of the
job) :-)



Temps are also a little high here in North Carolina lately. I'm about
done welding. Just gotta be sure to clean the sweat off the steel, then
add a little oil. But what will sweat do to a layup?


Moisture is bad and sweat far worse as far as lay-ups. The glass
fibers are very sensitive to moisture. Sweat not only has salt, but
oil in it as well. That can affect the layer to layer as well as the
internal lay-up strength.

I clean the surfaces with Acetone and do the lay-ups while wearing
surgical gloves. I was cautioned not to even touch the surface with
my hands prior to lay-up and after cleaning. If it will be multiple
lay-ups I use nylon or Dacron cloth as a peel ply to prep the surface
for the next lay-up.
