Carpet underlay question
 

My 68 is getting an RS kit from pelican. Question is the carpet glued onto the body directly or onto an underlay. I'm getting perlon. What's the go from those who have been there.
Thanks Lyndonhttp://forums.pelicanparts.com/uploa...1521528914.jpg

Combination... some spots have underlayment, some have none at all, and some areas have vinyl.

I would line the whole interior with the newer sound deadening. especially the rear seat area. You do not want the metal indentations to telegraph thru to the carpet. Also watch you cuts. I did my 67 with the same material - the pre-cut patterns do not fit the early SWB cars very well. I came up short on the back deck lid and the seat bottoms. Had to order raw material to place under the patterned carpet so that I would not have gaps

Thanks. I have heard of fitment issues.

DO NOT COVER THE WHOLE AREA WITH AN MODERN SOUND DEADENER LIKE DYNOMAT!!!!

That is about the worst thing to do. Water WILL get under it as some point, and it will cause massive rust quickly, as the water will not be able to evaporate. My rear seat area suffered this, and I pulled it out. A foam sound deadener would be good, as the water won't get trapped under it and can dry more easily, and you can feel if there is water in there. IMHO too, the read deck lid and vertical surface can use the sound matt for sure, but the seta pan wont really buy you much.

as an aside something like Dynomat does not need full panel overage. Strips on each panel will do as much as full coverage. It basically kills the "tinny'ness" of the metal, reducing the "ping" vibration related noise of the panel. Think of a stone hitting your floor pan. No sound deadening and it goes "ping" and rings/resonates. With something like dynomat or the factory asphalt it is more of a deadened thud. To lower the Db of noise overall though, you need foam. As I understand it, and I am no expert, you need them of multiple density's.

Are you planning on running the engine bay sound mat, and the deckled interior sound mat? If not I would say don't worry about sound proofing the rest of the car, as it would be like pee'ing on a forest fire. If you are, then certainly explore sound deadening other areas as well. Just my 2 cents.
