Hi all, I have a cheap (but not so bad for me) fengda bd-130. beside it's inclination to be blocked and don't spray (maybe it's only my fault 'cause I use acrylic and maybe I don't thin them well), it worked fine.

Untill the trigger became sticky and I don't know way, the trigger itself is in good condition, the piston moving good, and the air valve is normal, no strange behaviour.

But, when I insert the tringger in the airbrush it became sticky and it's difficult to controll the paint flow 'cause some when I press the trigger it remains pressed for a bit also if I release it. :(

Is there a way to solve this?

Do you have some advice to improve my airbrush untill I save up some money for a better one?

Do you have some advice for thinning correctly acrylics? I use water untill I have a milk consistency, but I've read that many use a mix of 50%-50% isopropyl and water and thin acrylic. 70%(thinner)-30%(color).

thank you in advace.
