Best cowl heat shield

[Flying Scotsman]

What's the best heat shield material to use on the inside of the cowling? I'll epoxy it and paint it, then want to put down some of the reflective material...but want to use the best material.

TIA!

how well plain old aluminum tape from the Home Depot aviation isle works. In addition, it's easy to custom fit whatever area needs covering. I touch mine up at each condition inspection, but it's really only for cosmetic purposes.

I use the heat shields sold at the local auto-parts store --- on the -10 and -8A, they have worked great!

I went with the stickybacked, heavy duty aluminum foil stuff Vans carries. Works for me.

this is the real stuff used on certified aircraft. sell what is left over on vaf. they have heat resistent glue also. they can answer any questions you have. do it right the first time.

This is what Dan Horton suggested I use. FiberFrax 1/16 thick mat from Aircraft Spruce (http://www.aircraftspruce.com/catalo.../fiberfrax.php
and the put Vans foil over the top. Cut the fiberfrax 2 inches smaller than the foil all the way around so the adhesive on the foil will have something to stick to. I brushed on a coat of epoxy resin all around the edges to seal it up. So far it has worked great. I had an exhaust pipe move and touch the cowl exit on a hour flight and it did no damage to the cowl.

I used this Cowl Heat Protector from Van's.

To apply it, I used a wall paper seam roller. Here are a couple of pictures:

The biggest difference between ours and some of the others is ours cost a heckuva lot less!
