Rob,

I think the 1/4" foam trick applied to the 235 cowl.  It
happened to me so I added the foam and 2 BID.
Unfortunately, over time the cowl continues to get heat
soaked except for the foamed area.  This "patch" then became
noticeable right though the paint.

Seeing (and fitting) the 320 cowl to my 235 I don't think
foam is required.  There are enough compound curves to
prevent oil-canning.

For scorching, apply some 1/8" fiberfax to the cowl in the
effected areas with contact cement.  The cement in a spray
can works very well for this and is available at most craft
stores.  After laying down the fiberfax into the cowl, spray
some contact cement onto the fiberfax again and put down
some heavy duty aluminum foil over top.  Extend the edges of
the foil and extra inch beyond the fiberfax.

This creates a heat shield that is thin and that conforms
to the curves of the cowl.  I learned this trick from a
Long-exe friend and it works extremely well.
