With or without?

I’m another fan of nylocs and the only time I use washers in this application his if I need to add a little mass for balancing purposes. I do however agree with Steve on the hermetite issue.

Over the years I have used up all my old Estate Agents foamex sign boards.

Part of one of Malcolm's old boards was, of course, the source of the material I've used between body and chassis

Hermatite and the other various jointing compounds are fine if used correctly. If they'd have been available in the 1920's and 30's I'm sure Austin would have used them just as modern manufacturers use them today.

Carpet, felt etc. between body and chassis retains moisture and helps rust. 

Very true, many chassis have quite deep rust craters caused by the felt layer.

I've used felt in the past, but soaked it with Waxoyl before putting the body on. Seven Workshops stock a suitable felt strip, B0582.

We stock a close cell neophrene rubber strip, that is adhesive on one side - I have found this to be very good and keeps the water away from the chassis. sold in a 5M roll so will do a few cars!
