Tomorrow is carpeting day. (standard issue FFR carpeting + whatever I find for the trunk later today). I'm mounting it on top of Cool It Thermo Tec.
I've been reading a number of carpeting threads and it seems that some use the 3M product and some use silicone. Left to my own devices, I'd probably go with the 3M77 as that's what the manual suggests.



I have both on hand. Any strong opinions either way? Any other valuable "lessons learned"?
