depends on how far you want to go and whether "correctness" is of any concern. of course you will want to remove any signs of rust and treat the bare metal to prevent any in the future.. http://www3.telus.net/68bird/rust_repair.htm many people put down some sound deadener while you have the seats, console and carpet out. it does make a big difference with road noise, heat, rattles, and sound quality in the car. http://www3.telus.net/68bird/sound_control.htm
be careful ;-) sometimes full restos start from simple beginnings..
There's not much to that stuff. Lay it down. Done. No glue or anything. I spent more time using Peel N Seal from my local home-improvement store to supplement that underlayment, because yours will only cover a portion of the floor. Glad I did. In hindsight I would have just used 100% Peel N Seal and skipped that stuff you bought, but mine was non-returnable so I went ahead and used it up.
These cars generate a LOT of heat from the floor, with the trans and exhaust running so close and almost zero heat shielding underneath. You definitely want that deadening in there at a bare minimum, plus more. For sound it's a relatively pointless exercise because it's a convertible...plus many of our cars run dual exhaust and louder mufflers. So it's not like you're building a quiet Cadillac...but focus on heat isolation, and from that perspective it is VERY nice to have 100% of the tunnel & firewall covered below the carpet...and that underlayment kit you purchased ignores the majority of the tunnel & much of the firewall.
There was a recent thread about using plain ole' radiant barrier at PY about a week ago. I was asking since when I replaced the carpet in y 69 in 1992 there was nearly zero underlayment in there and I never thought to put any in.

Is this what they are talking about? Is this a peel and place product? If not how do I get it to stay down?
It combines sound deadening and very good heat shielding. The aluminium is much thicker. The other products have less or no alumnium sub strat and work like those cheap astronaut thermal blankets e.g. they do not work. And do not stand up over time and some of them bunch up and buckle in high traffic area like the drivers side front seat.
Pontiac orginally had a craft paper backed tar like panels pasted to the floor pan and the carpet had a jute backing. Those together sorta kinda worked. For the cost of the jute pad and repop craft paper backed tar like panels - just get the dynamat extreme for a few dollars more
High end resto shops use it by the ton.
CAVEAT- it is hard as hell to remove and because of the thickness of the aluminum backing I had to use a dead fall rubber hammer to get it to fit around the seat supports. Also you need to plan ahead for bolt holes in the floor pan, particularly around the seat belt anchors
NO, istr810m, you linked the wronge Lowes product...THIS is Peel & Seal Peel & Seal
Read the reviews...many people using this product as a cheap Dynamat replacement. I put some in my truck's doors also while doing a stereo speaker upgrade. Working fabulous.
Found in the roofing/gutter aisle at Lowes. It's like a sheet of heavy tar/asphalt material covered by heavy/shiny aluminum foil. No R-value, but it's a good radiant barrier and the mass is a good sound deadener like asphalt...eliminates any oil-canning and tinny sounds/resonance of sheetmetal
Self-adhesive...once you press it down is is NEVER coming up again...poor man's Dynamat. 2 or 3 rolls of Peel & Seal will cover your floor depending on how critical you think it is to cover ever square inch.
Feel sorry for the next guy that has to scrape it off to replace my floors 45 years from now...hope it's not me.
It's flimsy junk and doesn't stick real well, but it offers another radiant barrier and has 1/8" of foam insulation to help control more heat also with a bit of R-value. Gravity and carpet holds it down.
So Peel & Seal sticks to everything...vertical, upside-down, whatever...forever. And that Frost King stuff just lays on the floor under the carpet. Then the felt backed carpet on top of that. Gives me a nice lush carpeted floor that doesn't get warm.
So that combo works well under my carpet and reasonably inexpensive when compared to Dynamat and other such products which I fully acknowledge are probably better...
