Any recommendations for quieting the inside of a '68 SB? I don't have any tarboard in the engine compartment.

Will this stuff work? --> https://www.jbugs.com/product/111898805.html?utm_c...GcQAvD_BwE

Or is that only for Type 1? Also been looking into some insulation for inside the car. Anybody have experience with the Quick Roof/Peal & Seal? --> https://www.lowes.com/pd/Peel-Seal-Instant-Waterpr...lsrc=aw.ds

Or is it worth the extra dough to go for the Dynamat? Having a hard time getting myself to spend $100+ on a couple sheets of aluminum insulation.

If there are good threads that discuss this please send my way :)

Years ago I did use jiffy seal / peel and stick from H.D. It was a bigger roll , 10-12 inch wide and 30-40lbs heavy. Similar to the Lowes stuff. It just did not have the foil on it. I did put 2 layers on the panels and inside of roof / doors / side panels and than silver heater duct foil tape to have a clean outer surface. Nice and quite and zero rattles. Still have lots of it left over. Roll was only $20 plus tape. Best deal ever. Just be sure to install it without any air-bubbles behind it. For the engine compartment you would have to get the hard stiff tare boards,

the add says it can be rolled up - the factory VW is stiff and 1/4" thick and does not roll up. Call them and ask

at this moment in time i dont have any sound deadening below the door cards in my fastback.... while the car isnt extremely noisy...i know i need something I am going to try that peel and stick from lowes. do the tunnel , the rear firewall (under the rear seats) and on the pans and see how that does. i know people have had extremely good luck with it.

when it came to my roof i used the aluminized foil/bubble insulation ... we had a couple 100+ days here and i have never been in a cooler VW in the summer

google Low-E insulation (EZ-Cool) installations
tons of hotrod guys use it to quiet and insulate their cars.
I have 2 layers on roof, floors, doors, rear deck, along with strips of dynamat type materials for vibration dampening. You can carry on a normal conversation in the car, and it stays relatively cool parked at work all day in the summer

if you're cheap, and most vw owners are, peel and seal will work ok. the internets are full or peoples that are cheap and installed it and were happy because it was cheap. they almost all just recently did it, they never come back 3 years later though, let alone 6-10 years. The stuff has been tested against other brands and it does work somewhat, but not as good as purpose made car sound deadening mat such as dynamat or a million other brands

I like this brand: https://soundqubed.com/product/q-mat-self-adhesive-sound-deadener-16-sq-ft-8-sheets/

One of the main reason i am using peel n stick - Peel and stick is thin and flexible and can be attached and pushed into almost any shape of metal vs the thick material. I have seen plenty of cars where the water got between the sound mats and floor pans. We all know what that leads too. However, it is more work if you do two layers and foil tape on top of that.

is the foil on both sides of the material?

Home De Pot peel and stick works fine. The issue will be if you do not like it. PIA to remove. I did not do the roof with it, I did the aluminium bubble EZ Cool stuff.

yes, you have to glue it down, it conforms well to shapes too.

Sounds like installer error to me. The butyl type is very easy to use in my opinion. And doesnt have the falling down issue of the tar roof type

I did not say "it is falling off". I never had any tar / butyl material falling off on any of my cars. I have seen it coming off because the surface was not clean when it was put on or it just got bridle over the years and starts to crack which is normal. All of that stuff sticks to any clean solid surface.

I did say if the material is too thick you can not push it into the shape of the metal. For example the floor pans. The material will just sit on top of the highest spot and water can / will run into the low spot and sits there. I have replaced countless floor pans because of that issue.

I put the tape on the floor. Slowly with a heat gun to keep it soft and push it in to all the grooves. Any sound deader will use the same technic and if it has a clean, painted surface to adhere to it should have a long life.

Yes, heat gun is the correct way to go!

If the OP is interested, he might try contacting Mike Fisher for some OE stuff. He's probably got some at his farm that should be reasonably accessible and easy to remove and ship.

I use Fatmat on all my vehicles. They have different stuff for a variety of things. Heat, sound, etc.
