I would wait and give it the time it needs for full cure. whats your hurry?
If the weather is anywhere near what you have hinted at out there in Utah right now, the cold is probably slowing it down. If your garage isn't heated in some way it may take awhile to cure. Otherwise, let it do its thing. ;D
whats your hurry?
Try a heat gun set on low and try to 'radiate' the heat slowly to help force cure the seam sealer.
Good to hear, what brand was the sealer?
I feel bad for ya man, but I think you should start removing it and redoing with a trusted brand. I have been playing the same game lately with 2k primers and now I'm going back to the expensive stuff I trust!!
