Hi all I was wondering if I need to do any extra prep work or add anything to help make my water based paints bond to the plastic models or should I try to reduce the tester paints with regular paint thinner if so what would the ratio be. Thanks in advance

If you are talking about acryl or acrylic paints then those should already be thinned for airbrushing. If I thin any of those (I use acryl a lot) I thin the paint even finer using rubbing alcohol. Regular thinner will not mix well with the water based paints and will not give you any good results. There is different thinners on the market made just for water base paints that you can use. My best experience was the use of the rubbing (isopropyl alcohol) and mix ratio depends on how thick/thin you want it. It also helps the paint set faster. Maybe a good primer surface first of scuff up the plastic with fine grit sandpaper before painting. I had acryl stick right to the plastic with not much problem. Just don't tape over it to paint another color or it will pull from the plastic when you remove the tape. Primer should be used for this type of painting.
If you are using the regular testors enamel paints than the mix ratio for airbrushing should be close to a 50/50 mix of paint/thinner.

Thank you very much for the info, I'll give it a shot then I was told by a different person on a different forum to use the adhesion promoter and that made a total mess of my models. I do have some water based acrylic hobby craft paints. But thanks once again.

I may have to give your ratio a try the next time I am ready to spray something. I've always followed the mix ratio on the can of thinner. This is on the side of the ModelMaster enamel thinner can Flats: 3 parts paint 1 part thinner. Gloss: 3 parts paint 2 parts thinner. Semi-gloss: 3 parts paint 1-1/2 parts thinner. (this one is not listed on the can but makes sense given the mix ratio for the other 2.) |

Chad I tried with the mix ratio on the cans and still didn't spray right. So when I asked my local hobby dealer he said he always did a 45-50% mix of paint and thinner. He has always had good results. I set my pressure at 20 psi and it works great. When I started to mix it that way I got much better paint jobs. And on the acryl paints I use a lower mix ratio with alcohol instead of the products made for thinning those paints. The alcohol seems to blend better than the produced products.

Well the reason I'm asking is that I have some thinner called S L X Denatured. I use it to make home made reducer for the water based paints but I don't know if it would work with testors paint.

It may work for the Testors/Model Master Acryl paints but I don't think it will for the enamel or other based paints.
