 Marv,
 Do you have the temp and duration specs available to show what kind of
 protection this product will provide??
 
[Go to www.nu-chemusa.com, click on the products link and see the data sheet for Thermo-Lag 3000.  We actually use 3002, a slightly thicker product, tested to jet fire standards.  Their docs claim a 1.5 hour rating for a .210" thick coating... our attitude is that we need to hold back the flames for 15 minutes. or about 15% of the time the material is rated for.  A 6X safety factor feels prudent, given that we are not coating steel beams.  Best thing is to read their data yourself and make your own decision.    <Marv>    ]
