Hi Daren,

: i've been told it is not advisable because of there being a higher risk of
: explosion than with paint.
: also, i've been told that the fumes are very toxic. the guy actually said
: "deadly".

The fumes consist of mostly Volitile Organic Compounds (VOC's). There is a high risk of explosion because spraying atomizes the VOC's which lowers their flash point. Watch out for pilot lights, sparks from switches and motors, etc.

As for their toxicity, it is not a problem because this is EXACTLY the purpose of a chemical cartridge respirator. They remove organic compounds.
