Make sure I have this right . the intumescent coating replaces the blanket?
How about
replacing the stainless/fiberfrax on a 360? What else?
And you wouldn't have to put up with compressing the blanket material
under
the mount pads. Yes? Brilliant.

[Yep, you've got the general idea. This completely replaces
traditional firewall treatments. And, as shown in the several photos I sent along yesterday, you fill the minor imperfections that remain after
application with micro, then paint to match your airframe. Like any body work, the better the substrate the better the finish. (The bluish
cast in my photos yesterday was caused by white balance issues and an incredibly blue sky just outside the hangar door where the photos were taken....
think WHITE, not light blue <g>.) We recommend that the coating be applied to about a 3/16" thickness... it does compress slightly under
the mounts so some people actually bond in a stainless steel area washer at each hard point and expose it just under the mount by removing the coating
there before it hardens. Like anything else, this stuff does have one minor down-side... its catalyst has a really bad smelll. Great
ventilation and a good respirator are required during application. <Marv> ]

Subject: [LML] Intumescent firwall
coating
I just noticed the post that Joe Trepicone sent through regarding our
intumescent firewall
coating. What he said about it is true, it does look
very nice and it's very effective. My understanding is that it was
actually
developed to protect living and office areas on offshore oil rigs. It works
well enough that it has begun to be
used in many more applications. I've
attached a couple photos of a typical Propjet firewall treated with
the
stuff. As you can see, it's lots nicer than a blanker <G>. A typical
Propjet firewall consumes about
3 gallons, at a cost of $395 / 2gal kit +
$210 / 1-gal kit, plus freight from Deland, FL. A standard IVP or
LEgacyu
firewall would probably only use a single 2 gallon kit, as neither has the
plug to contend with. Anyone
interested please contact me during business
hours at 386-295-9279 or drop me an email.
