Most excellent tip.
My liner is nothing like a hood liner at all, again -- like painted foam
rubber. I also read the MD-11 meeting notice caused by the SwissAir crash.
I hadn't thought about DOT approval. Good suggestion.
Arch sent me a nice reference to a product he found, and I'm going to call
and see who carries it in our area.
I'll also have to call someone at one of the SOB plants and see what they're
using.
Thanks !
Mark

Mark,
Pretty sure you've got something someone kluged up in there. My '75
generator compartment is lined with fiberglass insulation. Pretty similar
to
house insulation batts except it's a bit denser and the exposed surface is
partially fused together so it doesn't shed fibers. Some cars used it as a
hood liner in years past.
This stuff is 99.9% fireproof (unless saturated with oil). I've even
added
a thin layer (~1-1 1/2") of house insulating fiberglass on the generator
door,
which I think reduces the noise slightly. I'd suggest pulling out the foam
stuff and putting in something fireproof.
BTW, recent news articles regarding the flammability of mylar/plastic
bubble-wrap insulation in aircraft (M-D/Boeing have advised airlines to
remove
it at overhauls) make me think I'll stick to fiberglass and/or DOT-approved
stuff in the future.
Good luck.
