I'll agree with this permanent "bonding"--
I don't have the "hothead liners" I have the offroadhereos and you both use about the same velcro adhesive, for attachment to the hardtop-
My jeep lives in the Nevada desert at 115° during the summer, I've re-attached the velcro one time and seems to hold, but I would agree with the permanent bonding--
As a matter of fact, if you come-up with a bonding solution--I'll be a customer-
Thanx-Oh you weren't in business when I got my ORH kit, otherwise I woulda bought from you !!
