Is there any problem using a fuel tank sealer from an auto supply to seal the firewall as required?

This might be a question best asked directly to Van's especially if you are build E-LSA and not EAB.

The fuel tank sealant sold by Van's is flammable even when cured.

I used 3M Fire Barrier 2000 to seal the firewall, including coating all the rivet heads on the engine side of the fire wall.

This thread has a good discussion:

I used stuff from Auto Zone. Haven’t fallen out of the atmosphere in the last 9 years or 1100+ hours.
