Henry's 663 Application emperatures

[JohnF]

I "glued" one aluminum side to my Cubby in temperatures I thought might be too low, so I put two space heaters near the side for 24-hours. That seemed to work, and the heaters kept the air my un-heated garage at 40-degrees (F) overnight, while the metal was well above that. The metal seems to have adhered well.

I am now ready to "glue" the other side, but wonder what the collective wisdom is regarding using Henry's 663 at lower temps. The can doesn't say anything about minimum application temps, but I suspect keeping things warm would be a good idea.

Your thoughts?
