In response to an earlier question about these paints one of you stated you thinned them with water and/or alocohol. Current question: what kind of alcohol? i.e. — methyl (which is sold as shellac thinner); ethanol, isopropyl?
Tom
I’d think isopropyl, simply because of the easy availability.
FWIW, I have never found the need to thin them. They brush-paint and airbrush beautifully. The only time they have ever clogged my airbrush was when I was using reefer white (large pigment) from an old, mostly used bottle.
I mostly use water-based paints and Modelflex sprays much better than PollyScale (PS has to be thinned and their reefer white is very difficult to spray). However, there is only one hobby shop in this area that stocks Modelflex, so I use PollyScale a lot.
I also like Testor’s Modelflex a lot, too. They spray beautifully also.
Tom,I use Wndshield washer cleaner,it works well and the blue colordisappears,about a dollar a gallon at WALMART.
The yellow on this fishbowl bus is a mixture of Badger Modelflex Santa Fe yellow and red. No thinning needed. Just stir up the paint well, pour into the airbrush jar and you’re good to go. Test paint a scap piece of plastic or junker rolling stock shell first. [;)]
The thinner is an 80/20 mix of water/isopropl alcohol. The previous posters are correct, you normally shouldn’t need to thin Modelflex, but if you have forgotten to close a bottle and it thickens up you can use the thinner I described, it’s also good for cleaning brushes.
I don’t understand why so many folks seem to have an adversion to thinning paint, it’s really not a big deal: with a medium (#3) airbrush tip, spraying at 16-25 psi, any acrylic paint should have the consistency of milk, (Polyscale too).
Seems to me when they first came out, one reviewer who normally used straight isopropyl alcohol to thin paint found when he tried it on the acrylic paint, it turned to paint to a rubbery solid?!
Anyway, a little water will work if you need to thin it, but I think it’s advertising always claimed it was sprayable as it was…I’ve rarely if ever had to thin acrylic paint to spray it.
Windshield washer??? Good heavens, I never would’ve guessed that. Although I have not looked at the ingredients on a container I would have guessed windshield washer contains some kind of detergent which you certainly would not want to mix with paint — but I guess not.
Thanks for the wisdom.
