I live in south Texas and summer temps here are in the 100's. I'd like to add the pre-cut insulation pads to my JK's hardtop but can anyone give me advice on the best glue to use ? Vel-Cro, 3M double stick tape, or spray glue are NOT gonna last in this kinda heat. I'm looking for a 'permanent' way to install these insulation inserts that won't fail, later on, under extreme heat. Thanks.
