I have a large supply of Thompson’s Blue Angel high temperature 2”x6” sticks that I melt and pour into 3/4” PVC lengths to fit my STAR lubrisizers.
I had a hard time getting the lube free from the PVC!
I ended up using a heat gun to warm the PVC and pushed the lube stick out.
In the past I just put them in the freezer and they came loose without much trouble.
How are y’all doing it?
