I posted on the GMT400 Flaceblook page also.iirc LMC truck sells a repop if this in one of their catalogs. I wonder if that stuff is any good. I thing most are held in place by plastic push rivets. if they are placed in areas (not over the turbo) across the center sections for added support?
On a BMW motorcycle. One of the tank side covers had a cobbled affair that was not holding.Do you seriously think your hood is getting to 350f ?
Paint would be cooked off in a burn mark, right?
Begin with a turbo blanket. Their advantages are known and should drop the under hood temp to same as a gas engine with headers easily.
if just the plastic push pins are still the concerns use sone of the trim sheet metal screws with fender washers in place of the plastic push pins.
I have a box with quite a few of those in it. Different sizes.On a BMW motorcycle. One of the tank side covers had a cobbled affair that was not holding.
I shoved one of these through the hole and fixed that little problem right quick.
The one I had used a 1/4” NC bolt.
