Seam tape won't stick, suggestions?

Trying to fix the underbelly and the tape won’t stick to the belly fabric in this weather. The inspector, as usual, cannot offer me any suggestions other than it has to be done before he will pass it. The tape we’re using in the 6" wide material specifically for belly repairs. It stuck just fine when the weather was sunny and warmer but won’t stick when the temps drop and it gets damp.

Anyone got any suggestions?
