I think for the most part what you need is just some sound deadening material like the second skin in the OP or some cheaper foil-backed stuff. over that you can always put some vinyl and seal it with some armor-all leather/vinyl conditioner to keep it from soaking in moisture. I'm sure if it works for seats it'll work for a hard top.
As for the carpet mod thing: I used some rubber 19# carpet pad and some thinner indoor-outdoor cheapo carpet. Shouldn't mold, it's a rougher open-nap fabric compared to most indoor carpet and it should dry out pretty quickly. The rubber pad is waterproof so I'm not worried about that. I used some locktite medium-strength adhesive (description gave me the feeling it was stronger/better suited for the materials than the 3M 90 series adhesive).
The fiberglass-to-carpet pad bond was indestructible...as soon as I touched the pad (glued both the top and the pad) to the top it was stuck on, and tore a little as I tried moving it around to fit better. I cut out a strip for the middle support...and in retrospect that was a big mistake. I should have cut off material later on to avoid the bulge. But live and learn.
The carpet-to-pad bond wasn't as strong...and I got a small sag in the middle when I put the top back on. Hopefully after a night of drying with some wood pressing it back into place it'll be better.
Tomorrow night I'll take it for a quick spin down the road and see how it did. I'm assuming a 20# carpet pad is going to deaden quite a bit of noise on its own. If the difference is noticeable, I'll take it back off and do the four corners to complete the job and hopefully disguise the rushed cuts that I made.
good idea but I would do the whole top interior instead of just a rectangle. Try using a brush on adhesive instead.
I do stuff... 2000 XJ, 32" BF Goodrich KM's, 3.5" RE Lift, vented hood, Racing Radiator, Tranny Cooler, 4.56, stock axles, rear disc conversion, skid plates, rock sliders, cold air intake and throttle body spacer, delta headlights w/ 55w HID's, front bumper.
