Thickening paint?

Seems to me that if you want thicker paint, leave the lid off the container for 30 minutes, while stirring it occassionally to avoid developing a skin across the top. After 30 minutes, test it on some spare spars or white board. If not thick enough, lather-rinse&repeat process.

This way, paint is paint with no un-natural additives and probably easier to clean from your spray gun and/or brushes.

I agree with all the answers you've gotten .

     Just like to add this though . If you are really desperate to thicken paint , Let it settle very well until you see the semi - clear liquid in the bottle .This is the " Vehicle " I/e the liquid of the paint ,or the base .Now remove some of it with - out stirring up the pigment . Viola ; Thicker paint .

   NEVER remove more than half , or you'll have an un-manageable mess . I used to do this and still do for making paints I could texture with stipple brushes ( just like oils only with enamel . )

Point here for all , I have been doing this since Testors original Non - Flat bottled paint .Then I would take Talcum - Powder and put it in the paint till I had a good heavy flat - Like for undercarriages on trucks and cars .You know the old " Undercoating "

Most paint bought new are not "accidently" bottled too thin. It's paint and it's suppose to be that way. Have you ever tried painting using thicken paint? That's like opening a bottle of paint without a good stirring/mixing and it comes out all gooey.

On a side note, the best way to use Testors Contour putty (the white grainy stuff) is pick it up and drop it in the circular file beside your desk.

Don't do that.  If the paint is too thin, just add more paint, not putty.

If you have no more paint, buy more!

Mix putty to enamel paint? Why? Makes no sense. If airbrushing enamels, you have to thin it regardless. I say no to adding putty to paint. You're asking nothing but trouble.

I haven't tried it but i would think the putty would change the color of the paint and make it gritty as well.
