Try testing it with samples of your products, then you will know. That's what Dan has done with numerous products (and most likely your product) and shared his results with us. Thanks Dan.

Hey Mehrdad,
It's from Titanium Goat, a lightweight backpacking supply company. Check out the top of the first post for the direct product link.

titanium needs pressure to help it burn. when exposed to normal pressure under the cowl it should not burn.

Thanks for the info.
Do you recall specifically what stainless tape you used (or the supplier)?

Don't really want stainless tape for this application. Melting is desirable to vent the overlap seam.
Take a look at Polyken 339:

or Polyken 345SW:

This makes sense but what about the adhesive? Wouldn't the adhesive "melt" or soften and allow off gassing in either case?

Fair point. Probably yes.

Belly fireproofing
What size area would you or did you cover for fireproofing the belly? Specifically:
Wider than the cowl outlet at the front? Full width of belly?
How far back from cowl outlet did you insulate?
Did you keep it the same width front to back, or taper towards the rear?
Thanks.
Johan
