Some time back someone here (sorry, don’t recall
name right now) kindly suggested the 3M strip caulk for sealing air leaks around
the oil cooler (remember “gorilla snot”?). It looked good, but I
wondered about its behavior at 200o+.
I set up an aluminum angle with about a ¼” gap to a
block of wood (simulating fiberglass over foam); filled the gap with a roll of
the strip caulk; stuck a lab thermometer into the strip caulk; and heated the
angle with a torch. Slowly heated it up to 220F. The stuff did soften, got
stickier; but showed no signs of changing shape or going anywhere. Still firm
enough to hold some air pressure.
Today it is going into the gaps around the cooler.
Thanks for suggestion. Find at: http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Product_Code=3M8578&Category_Code=JASS
