Also realize that most chaulks use acetone to cure faster, not good for back sheets. PV adhesives are air cured and take a lot longer to become full strength, at least 24 hrs under ideal conditions! PV804 is bomb proof, I have done adhesion tests on junction boxes And I literally had to destroy the module to get it off....back sheet sticking to the J B still! Not cheap...$8-$10 a tube!
