I'm sure others have tried this, but I wanted to share my positive experience.
Yesterday I spent seven hours cutting and applying the aluminized heat barrier recommended for the interior of the bottom cowl, which I bought from Aircraft Spruce. It is recommended that the seams and edges be sealed with high temp RTV, but before I did I conducted some tests using aluminum tape. The results were promising, so I went ahead and sealed all the seams and edges with the aluminum tape. I used a plastic roller (bought for fiberglass layups, but never used for that purpose) to firmly press the barrier material onto the epoxy layer applied to the raw interior the day before. When I used the roller to also apply the aluminum tape, it worked perfectly to bond the tape and blend it into the panels. I'm hoping the glue on the aluminum tape will hold up to the heat exposure; it is designed for HVAC applications so it should. In any case, the results are far better than expected. It's been awhile since I had a genuine "Yee Hah" moment in the shop... but this was one of them.
(Darn it... Google Photos is acting up again... my shared folder isn't sharing any more. Working on the problem)
