Matter of fact,
You have me going to make me another one! Mine has gone to the mtsterious
mech brother of the sky...nah I know who has it! They are very simple to
make, and hey when you are working on the line and have to prime a fabbed
part and do not want your job to look like crud by brushing on primer it
does a great job and clean up is a snap. And if you ever have drug out the
paint guns you know you spend as much time cleaning the gun than you spent
shooting a part!
Take a good old harbour freight air sprayer with the trigger handle on
top..just a few bucks...rig up a small plastic tube that makes it up into
the air stream. Using a small hose clamp is a good way to keep it in place.
Stick the tube into a cup of primer and fire away!!! To adjust the
coverage..very simple..move the tube up or down in the air stream. Works
beautifully!!! Cost practically nothing, and clean up consists of just
cleaning that little tube off!

Mike ,
you may want to try some surplus aircraft stores. We used to use these
little mini sprayers ,..actually guys would home make them as well,...but
it just used a simple plastic cup , or even could just spray out of a
paper cup if you want. Very good for small parts and such. If you have no
luck , let me know...see if I can locate ya one .

I'm just about ready to paint a very extensive amount of metal work
myself, and I also plan to use this method for the parts I'm not coating
in appliance epoxy.

The biggest advantage with the cheap airbrushes, I'm told, is that you
can mix different colors or even solvents in baby food jars. I've been
told that you can keep the mixed 2-part epoxy in a refrigerator and it
won't set up so fast. So if you don't get to everything you thought you
would today, you won't necessarily waste as much paint.


I have been using PPG two-part epoxy primer, applying it with a Badger
airbrush. If I am spraying only small parts, I can mix up very small
batches, using measuring spoons, as it takes only small amounts of
primer.

I have been able to store the leftovers in my freezer and use them a
couple of weeks later. I have found the individual-sized (1 oz) jelly
jars that good restaurants use to be great for this purpose.

Lacquer thinner is good for cleaning up the equipment, although I have
to remove the needle and tip occasionally and clean them up.

The airbrush certainly beats using a touchup gun!
