Very good advice, as usual. I got exactly what Vic describes, some blistering on the paint. I added some heat shields on all the exhaust pipes that are anywhere near the cowl - seems to have helped. Adding the layer of aluminum shielding on the cowl looks like a good idea as well!

Thanks for sharing these videos Vic. They are super helpful to this first time builder :-)

Apologies for the comment I inadvertently deleted. The aircraft spruce part number for the heat barrier is 08-00600. It is $27.50. Vic used 4 for the lower cowl on the RV-10.

Good tip, thanks

How about using Fiberfrax? Less weight, thinner so it will form to the shape of the cowling and a good heat insulator.

[@baselegaviation1614]

that works too.

Maybe it’s just an artifact of the video, but how did the inside of your cowling get its copper color?

[@baselegaviation1614]

I think it just the lighting coupled with a bit of red paint overspray.
