Ammo of Mig Paint and Tamiya Primer Compatability

Hi all,

I am building the Aoshima 1/350 Thunderbird 2 for my grandson, and have run inot a bit of a problem with the painting.

A fair portion of the parts are molded in clear plastic, so, I sparayed them with Tamiya grey primer from a rattle can.

I mixed some mig thinner with the paint after giving it a good shake (the bb was rattling around) but it appeared to clog my Aztec airbrush, when i got it going the paint would not adhere to all of the surface, it appeared as if there was oil or grease on the surface, which was not the case.

Is this a compatability problem with primer and paint? Or, have I messed up with my mixing?

Can Mig be sprayed straight from the bottle?

Thanks in advance.

Hi!

To answer as best I can, yes MIG paint can be shot without thinning. You may have caused the problem by thinning it. I have had MIG paint not want to adhere or to bubble up and not lay down smmoth for me also with other thinners than Tamiya so it may be how it is. try shoothing without thinner and misting it on to begin with. hwen there is a thin coat it adheres to itself better. Hope this helps. Let us know what you find.

Hello, Bill. Sorry you had that problem. You didn’t say what brand of paint you added the Mig thinner to. I’m assuming you weren’t mixing alcohol/water based thinner to an enamel paint. It does kind of sound like that’s what happened, though. In that case, the paint and thinner never did mix and sometimes you were shooting paint and other times thinner. If that’s not the case, it’s likely the paint and thinner weren’t compatible. Most of the acrylics out there are very sensitive to thinners. You really need to use the same brand of thinner as the brand of paint to avoid the kind of problem you had. Of course, you do end up with a half dozen different brands of thinner when you do this, but it avoids the problem you had. It’s easy enough to start over. Just soak the parts in Windex. The acrylic will come right off. If it’s enamel, that will be a little more problematic. I hope something in this was helpful. Barrett

Hi Barrett,

Sorry the paint was Mig, I’ll have a go with straight paint, would a retarder be of any benefit?

I’ve used vallejo thinner with ak and mig paints don’t use alcohol with them or you will get a gummy mess

Bill, Well that adds to the mystery, for sure. I’m sure you mixed it well, so I don’t know. I’ve used Mig paints. They’re very good. You could add a retarder, but I don’t see how that would help with what you described. Someone with more experience is going to need to weigh in here. Barrett
