The coverage needs to be fairly extensive. I also have a bolt-on heat shield where the exhaust pipe passes close to the cowl. -------- Dave Moore RV-6 built and sold RV-10 built and flying Read this topic online here: http://forums.matronics.com/viewtopic.php?p=469578#469578 ________________________________ Message 3 _____________________________________ Time: 05:59:44 AM PST US From: Sean Stephens Subject: Re: RV10-List: cowl heat protection In addition to the reflective foil I painted the inside of the cowl with a few coats of white high-temp grill paint available at your local home store. I don't have a 1000 hours of testing, but so far no issues. -Sean #40303 > dlm > May 23, 2017 at 9:13 AM > I used a silicon backed layer of fiberglass mat; after 1000 hr. it was > OK; no apparent delamination.
