I  use Behr latex and 'seal coat' it with Minwax water based polyurethane (3
coats) and get resistance to 10% nitro.  I have NOT tried it on fabric yet,
but will this summer.  I thin with water and add a couple drops of soap for
spraying.  There was an article a year or two ago in MAN that has all the
info you are looking for.

Good luck.

I sprayed my 1/3 scale Fly Baby Biplane covered with Coverite with regular
white for primer then the color(s).
I used Bear brand Latex Enamel and works OK...Gas does not seem to harm it,
although it still feels 'soft'. I should have painted some type of clear
over it as the black from the exhaust is discoloring it some.... and where I
handle it the most (Vertical fin) the color is smudging/coming off.....

I covered cloth with Behr latex, thin with water and used latex flotrol
(some say soap or windshield fluid doe sthe same).  Sprayed great.

Clear coat with Nelson hobbies clear.

Hard as a rock, no problem, using gas

On 2/17/2004 11:31 PM Ted shuffled out of his cave and grunted these
great (and sometimes not so great) words of knowledge:

I usually use a flat latex - the brand doesn't seem to matter at all (I
have used various brands).

I would suggest using a primer.  It isn't really necessary for fabric
though.  If you do use a primer, I would suggest a "High Build"
automotive primer applied LIGHTLY.  When dry LIGHTLY sand with 320 or
400.  This would be used primarily to help hide the overlap seams.

For thinning I use about 1 1/2 oz of "Flotrol" per quart and windshield
washer solution (do not use window washer solution if the paint is white
- it will make a SLIGHTLY noticeable tint in white paint).  For white, I
use regular water with about 2 drops of liquid soap added.  Start with a
50/50 mix and adjust it from there for your spray gun.  I normally spray
at 20 - 25 psi and NEVER exceed 30 psi (I thin it down more to spray
properly at 20 - 25 psi)

Using gas you will not need to clear coat it.  Remember that latex takes
about 30 - 45 days to fully cure (depending on temperature and humidity)
