Subject: creating heat within air

we currently trying to produce a short film based upon ancient indian 
mythology "mahabharat" and are trying to produce some real life special 
effects. we want to simulate events with using less computer animation as 
possible because we want this to look as real as possible we dont want to make 
some cheesy movie. 
 
we are currrently trying to fire arrows at targets , but we want the arrows to 
catch alight within flight, or maybe actually heat up when fired and stay 
alight. do you know of any special coatings that we can place upon the arrows  
that would allow us to do this?
 
 
if you could help at all this would be really appreciated,because we are really 
excited about making this movie
 
 
please get back to me if you could sir
 
thankyou
