They seem to keep changing the heating part. The first couple of bottles I had said to warm the gun first, a couple in the middle said to heat it prior to applying it when you were going to store the gun, and the last couple say nothing about it.
Ive been using it for awhile now, so now I dont even bother. I dont notice any difference in performance between the guns I did heat, and those I didnt.
