Marv, looks "cool".
In my understanding intumescent paints are designed to (if they get really
too hot) make an expanding ash like those old "snakes" we used to play with on
July 4.   Is that right?  If so, what happens if you are airborne and you have
massive airflow against the firewall.  Does the ash stay in place?   ....or
would it work better with a blanket over the paint?

[The application process includes a layer of glass fiber mesh sandwiched in the middle of the coating, ostensibly to keep the material together after it has expanded. This isn't a spray-on coating, it applies more like bondo.   <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.
