[F500] Poured Seat Upholstery

[dogill80 at sbcglobal.net]

It seems almost sad to invade the sanctity of these vital dialogues but, I 
need an opinion(s):

I have poured a seat and now I must cover it to protect it and make it 
comfortable.  I saw nothing in the GCR that states any stipulations on what 
material I must use to cover the seat.  Must the material be non-flammable? 
Is there anything INFERRED in the language of the GCR?  Does the risk 
justify nomex or other non-flammables?  I know we carry flammables but, 
those liquids are kept in safe containers (at least on my buggy they are), 
I'm inside an aluminum/steele container, and I'm wearing a fireproof suit.

Assistance/opinions please.
