So, as others have said, I put it in the oven on low to improve flow. I don't know if it helped because it was thick as stupid putty but very sticky. The outer shell is aluminum and I've tried and tried with my good sealing frames and the stuff hasn't budged. So I went the other way, got a pair of tin snips and cut off the end of the pipe, put on nitrile gloves, took my inner child and started smearing it on the underside of my solar panel, plastic legs with no drill, and the roof. RV.Note: The working time is about 35 minutes. All of the product must be used within 24 hours (it also states that the expiry date is only 9 months). up to 12 days. I found a strange stopper in the tube I received (note that because the tube is made of alum, the tube looked like paper and was attached somehow. I would never have known if I hadn't cut the tube open, but it may have clogged the nozzle and left half a can when I thought I was done Things seem to be going well if anything changes I will update my review.
