Mission Model Paints Poly Additive Question

I've seen a few questions about it here that were answered. I have a little experience with it, but I'm not that good of a painter or modeller yet so I might not be able to help. I just followed the instructions on their website and watched the youtube videos. 

You might also try putting the question direct to them via the contact form on their site, or facebook. I asked a couple of basic questions that way and got very quick replies from them.

I have been using the paints for quite a while.  I had decided to make a batch of thinner and poly mix and keep it to make mixing easier.  When I added the two together this is what I got:

I contacted Mission Models and they said my poly was bad.  I ordered a new bottle and when it came it does the same thing.

The interesting thing is that when I add iin paint it all seems to "mix together" very well.  I was wondering if you could mix some poly and thinner together and see if you get the same results.  I am told that this should not happen, but I have tried two bottles with the same result.

Thx.

I’ve been using Mission Models paint since the LHS started carrying the line a couple of years ago. I’ve never used the poly additive to the paints for airbrushing, nor ever felt the need to do so. Their paint airbrushes perfectly fine using solely their thinner.

This is somewhere around 5:1 thinner to poly. The color in the photo is a little off because I don't know what I'm doing, but it's a thin uniform white color.

Thank you very much for testing this out.  Living in PA and the shipment coming from CA, iy came by air.  I have been told the poly cannot be allowed to get below freezing probably the issue, but air would always be an issue at altitude.

Thanks for that info.  I will try spraying without the poly.  I read it is supposed to help flow as well but I will see.  I do really like this paint.

Happy to help. They also say heat over 80 can kill the poly, so maybe it sat in a hot warehouse all summer. Good luck!

I am a newbie modeler, but I had a good experience airbrushing a Spitfire with Mission Model paints thinned with Vallejo thinner. They thinned and sprayed very nicely.

That does seem to make quality assurance very difficult.  Considering you have to buy 2 oz which when dispensing a couple of drops at a time will last long beyond the life span of the product.

I'm glad to hear you don't need to use it.

I actually don't mind their thinner at all.  The thinner makes clean up very easy.  I do really like the paint.  I cannot use laquers with the fumes being too much.

Do you guys mix it in a separate cup or right in the airbrush?  I mix it in the airbrush cup as I have not understood why you "need" to mix it in a separate cup.  Seems to me that wastes paint.

When first trying out new products, and especially if I am experimenting away from recommendations, I mix in a separate cup first to make sure it will not turn into some potentially clogging mass. If that works well, then I’ll pour it into my airbrush cup for use. Any subsequent mixing with those previously tested blends are then done in the airbrush cup.

I mix it in a separate container. Mainly because I'm still getting the hang of it and it's one less thing to troubleshoot when the paint doesn't go well. The waste issue is very annoying though - I've tried mixing in a 5cc syringe, just to get the measurements right and so I can get the most paint back out of it, but it is a pain. I'd love to get to mixing in the cup, seems to get you more time painting and less preparing & cleaning.

Yeah - almost seems too delicate to survive. I kept mine in the fridge all summer just to err on the safe side. I bought it from SprayGunner last April, and it survived shipping from Florida to Seattle. Maybe just good time of year for shipping.

Just keep the poly in the fridge, it will stay in good shape in there.
