Well that was a pleasant surprise...

Digging into my '63 Avanti project . The car has been in the weather for about 2 years and carpets are damp. Started pulling the carpets and spare tire to deal with typical rust and was surprised to learn the car is fiberglas in those areas too (my only prior experience with 'glas bodies was with a VW dune buggy which of course had a steel floor pan). So it looks like I will have less to deal with on the inside than I thought. I may still do the usual Dynamat treatment to quiet things down

Over time your Avanti can become musty smelling inside from damp carpets.  That musty smell can be hard to get rid of.  The carpets can also rot.  I use DampRid (WalMart, automotive/RV section).  It really does work.

Others have reported the effectiveness of DynaMat (& similar products) in noise reduction and also heat reduction.

So far this one smells fine and the carpets will dry out quickly, only a small portion got damp. I found a couple of large rolls of stick on roof underlayment at Lowes for a giveaway price. It's exactly the same thing as Dynamat and works well.

There is a product called ''Ozium''. It seems to mask or kill Any Odor.   Available at Auto Parts Stores.

I use it liberally, but a warning, just a few squirts will drive You out of the car... It's very concentrated. I'll juice the car interior down and close the doors/. An hour later I'll try to get back into it.
