Can anyone tell me what the material is that the mid 70s Cessnas used
for the interior plastic? We have a couple of cracked pieces we would
like to repair. I also remember reading a good article in one of the
aviation mags that went through the rebuilding of a really bad
instrument panel plastic cover in the last year or so... Anybody
remember which one it was?

Gerry Mader of REDAM makes a product called POLYFIX that will repair
any thermoplastic. Wicks used to sell it. It comes in different size
kits, depending on the number of linear square inches of material are
in the kit.
