Thread: sound proofing

My 2a has some modest soundproofing.

1. Seals on the bonnet sides
2. Fit neoprene self adhesive seals to all floor/seatbox joints
3. Transmission tunnel cover off late S3
4. Cab roof sound absorption lining of late S3
5. Deluxe trim on doors
6. ensure all holes in the bulkhead are blocked using new rubber plugs etc.
7. New gasket under pedal boxes
8. Adjust tappets
9. 10mm closed cell foam on the underside of the seat box lids.
10. Rubber floor mats cut to fit.

Result is little engine noise, most obvious noise is transfer case, overdrive and depending on surface, tyre noise, plus wind noise as the speed rises. Fixing air leaks on the standard door seals is probably impossible, but I can probably improve it.

John what did you use to s

and what are these neoprene seals of which you speak in item 2 ?eal the bonnet sides and back ?

Forklift battary box rubberized paint is what you need,Lancing Bagnall used to sell it(used it when servicing them some years ago) good finish and sound proofs good for hosing out the inside.
