    Hey all, so I was wondering, I just recently bought myself an Iwata eclipse airbrush as was trying to AB tamiya's smoke acrylic onto Sidearm Sideswpie's window, and it pitted on me. Now, ya I thinned it down like I would have for testors acrylics, was that wrong to do?? I just can't grasp why this happened, because I thinned my testors acryls down the same way, and I get they are different formula's but it all should still be the same consistency for ABing, right??? Any help would be awesome, and thanks in advance ladies and gents!

    I had this happen with me on my old Badger AB, I just kept thinning it until I found the right consistency that was right me, I would suggest doing the same thing.

    Thing is, I'm scared that if I keep thinning, its going to be to thin then. I mean, is already pretty thin as it is.

    Pitted?

    Is it orange peeling or fish eyeing?

    I never need to thin Tamiya paints...what are you thinning it with?...what pressure are you spraying at?

    I suppose it could be more of a fish eye type of thing, but it's like.. the fish eyes are popping and leaving the lower half of the air bubble?? And I thinned it long ago with alcohol, and spraying it at about 25-30 psi I think.

    My experience has been that Tamiya paint needs more thinning than Testors, and that paint generally does not go on smoothly above around 15 psi.


    I'm also not sure if actual alcohol/rubbing alcohol is the best thing for thinning paints when they're being airbrushed.

    Dedicated model paint thinner might be better. I've been using (odourless) Bartoline, and it's worked well enough.


    Just my .002 cents.

    you did thoruhgly clean the window before paiting right? mold release on the toy can do that. I've never had a real probelm with fish eyeing when i clean the surface properly.

    Thanks, I'll take this into consideration when I go to my work area tomorrow to repaint this thing..

    Yea, lol, I did. not only did I soak it in rubbing alcohol, but I sanded it and buffed it down a bit, then soaked it again in the alcohol to remove any grease that was put back on from the buffing compound.

    Thanks for the info guys!!

    Might I suggest, using Future polish to thin with, I thin all of my paints with it, and I never had a problem with it pitting at all, it goes on smooth as hell and because of the Future being a polish to protect floors and such, you won't need a clear coat.

    I haven't heard any complaints about that stuff yet. Maybe I can borrow the cash to go buy some for this stuff.

    If you can get a container of it, then awesome, I love using the stuff, I've actually carried the technique over into my prop building when it comes to painting them as well.

    I think people use alcohol because it evaporates very fast.

    I use rubbing alcohol to thin my Tamiya paints...just a little will go a long way... and fish eye will be caused by "oils" or solvents on the surface or coming through the line in the airbrush....

    if both of those are clean, then you should have no problem as long as you are spraying in light coats.

    Thanks dave, as far as I can tell the ab is clean, and I know for fact that ther surface is clean. Its been soaked, scuffed, buffed and resoaked, so I'm pretty sure it isn't the part itself.

    Are you using an inline moister trap ?
    I know my Airbrush spits out alot of moister, If I forget to use a moister trap.
