Seeing as I had a little bit of trouble getting Mega Mat to stick to the ceiling, I decided to do a little experiment and try to find the best adhesive for the EZ Cool that I purchased. The makers of Low-E recommend using 3M General Trim adhesive, but I couldn’t find the exact product at any of the local auto supply stores, so I picked out four comparable products for the experiment.
Permatex Heavy Duty Headliner & Carpet Adhesive; Loctite Professional Performance Spray Adhesive; 3M Yellow Super Trim Adhesive; 3M Hi-Strength Adhesive. All were between $10-13, except for the 3M Yellow Super Trim stuff, which was $22.
And the winner? They all work just fine! I waited a few hours after sticking the test squares up to see how easily I could rip them off, and they all seemed to be pretty well stuck. I’ll try blasting them with the heat gun tomorrow to see if any of them release their kung fu grip under high heat, but my prediction is that they’ll each hold up nicely.
I went ahead and put up insulation along one wall, using up the entire can of Loctite Spray Adhesive in the process. At this rate, I’ll need about 10 cans of adhesive to insulate the entire van. I’ll use the cheapest stuff on the floor, and the best gripping stuff on the walls and ceiling.
Compared to Mega Mat, EZ Cool is incredibly easy to work with. It’s even―dare I say it―fun to install. Famous last words.
