I also wouldn´t use any 10 buck gun to give the final layers on my cars... Not because itis cheap but for the fact that you have to trust your gun to do those final layers.... I use SAGOLA guns and my 1.4 one is the queen there... I keep it as clean as new etc... I love this gun most of all because i trust it a lot and i know how to paint with it...
In the Uruguayan market there are several cheap guns... i believe the brand is Flourish... I have 3 or 4 of them because when i started with this i couldnt afford a 800 buck spray gun.... well...that cheap ones compare with the ones i´m used to use now are garbage... the main issue is the shape of the drop shape... in here we call that "orange skin" when your paint seems to be too thick...That makes you wetsand A LOT and that is not good not only for the ammount of time you have to do this extra work but for all the material you are throwing away...
I think this 9 buck gun worth a try definitely but as i said before, if i were you guys and you are starting to do paintjobs, i wouldn´t start with this super cheap gun because if you do not handle the technique very well, a cheap gun wont make things any easier...
It would be great to get one of our pro members and friends to try one and then give a objective resumate on this gun... I´m sure this can work well for some minor parts anyway so, for the ammount of money that this costs, it is worth a try...
You guys in america should have a semi pro line of sprayguns for kinda 100 bucks, isnt it?... Well.. that is what i´d look for to start... a good but not a "ferrari" spray gun!
