Ammo One Shot Primer issues

[FlashGordon25]

The point of using that analogy Dave (Gern) was to illustrate that no matter what pressure you shoot it at water based paint will at some point gum up your paint gun, airbrush what have you.....it is the nature of the material itself. This explains why there are so many additives available to keep it from drying out while using it. The best one can hope for is to get the job done as quickly and efficiently as possible.

It definitely is the case of rushing to plaster it on before it dries in the airbrush and clogs, despite retarder/thinners etc.

Aaahhh. Now I'm with you. I thought it was maybe some sort of misprint for 30.00 PSI - then I thought nobody uses A/Bs and sets the pressure accurate to 2dp. Then I got totally lost! :upside: :upside:

I agree Dave , thought Rick had been at the bourbon again, or the thinners .

Matt I had problems with tip drying, didn't want to use solvent paint as don't want to have to wear a mask anymore as had to at work when spraying cellulose.
I had problem after problem, tried different combinations of mixes, even bought another ab. In the end started to use 3 rd Gen AK paints and bought a Neo ab .
Since then I've had no problems, it had got to the point where I dreaded the thought of using the ab.

Mine is an absolute dream to operate and it never lets me down. Bought it back in the early 90's.....dual action .....siphon feed. Of course I use those "smelly" non environmental friendly solvent based paints that are slowly being legislated out of existence.....but they get the job done even if I have to look like Darth Vader in the process........."Luke, I'm your father"....etc. Rick H.

WELL i think all you guys with A/B have the patience of a saint to put up with usein them as a freind let me borrow his an yes i dont know zilich about A/B 's as i have not used one before but he mixed the paint in the A/B jar an i treid to use it an it was not very good an kept stoppin sprayin an the compressor kept cuttin in an no spray at all an yes i know i make a lot bigger models than what you guys make but for me id rather use the ole rattle cans as ive hardley ever had any trouble with them its just point an spray but yes i understand with a A/B you can spray very small areas an they are very good for that so all you guys have fun usein them but they are not for me but this is just my opinion an im not tryin to upset anyone so have fun with them

Funnily enough, my issue with acrylic primers isn't spraying them, it’s sanding them if any remedial work needs to be done. I’ve switched to them for my figures, but will still use cellulose primers for tanks, aircraft, etc…..
Acrylic primer (or paint) and isopropyl alcohol is a bit of a no-no though. It tends to turn the paint from a solution into a colloid gel (think gunk).
I always start an acrylic spraying session by running at least one load of water through the brush and spraying until the brush is completely dry….this removes residual cleaning agent and minimises my spraying issues.
