Hello ,
I'm Bigbri's friend and yes I'm getting good reults at
a very low cost.

I'm using a cheap run of the mill single action Badger
airbrush. Latex paint will "flow" out for a time after
it hits the surface ,(remember it's thinned with water etc)
and you can get a nice even coverage that's uniform.

Practice on a large piece of glass,let it almost dry wipe off
and do it again until you develope a system that works for you.

Use several light coats rather than one heavy wet coat
and don't lay it on too heavy. Just enough to do the job

Bigbri is correct about the drying , let it set several days
before masking trim or exposing to fuel .

Good luck

ps Bigbri...... and you didn't think that I could type.....HA !
