Ha, as stated by someone else dont bother with the spotlight spray on. or the K&H spray adhesive, I got this great stuff (Permatex, Body Shop, Heavy Duty Headliner and Carpet Adhesive) $20 for a spray can, adjust nozzle to spray one can for the foam, one can for the fabric.
MY first attempt fell off the next day and that was with the spotlight glue, it said permanant bond, I sprayed both materials too.
I used suede (red) and am currently spraying the interior to match.
Thanks for the HOWTO I would never have tackled this on my own without it.
