Rob,
    I had some scorching where the exhaust tubes exit.  I attached a layer of
left-over firewall insulation (fibrefax) with the red, heat resistant silicon,
on the inside of the cowling.  It worked.
    Also, I used several tubes of crisscrossing carbon ribbon folded 20-30
times to make a tube the size of my little finger to stiffen the lower cowling
around the nose gear cut out.
    I also developed a small crack about two inches long that started where the
NACA scoop was installed.  I routed out the crack, filled it with epoxy and
flox and put patches on the inside.  It seems to be holding.
    The cowling screws are enlarging the holes as I remove and replace the
cowling (countless times!).  I've since started using the stainless tinnerman
washers.  Jim Michaels put a couple of layers of fiberglass along the edges.  I
don't know how it is holding up, but it sounds like a good idea.
