Painting and airbrushing

Heck no!! It strips the paint, it doesn't thin it too well. I treid this for myself with disastrous results. You can use water instead of the Tamiya thinner if you don't have any but I highly recommend using the thinner. That's what it was designed for after all. Hope it helps buddy.

I haven't used it myself however many people do use Windex with very good results.

I normally use isopropyl aalcohol for thinning. For glossy Tamiya paints I use Tamiya thinner because alcohol will cause them to dry flat. For PolyS paints I follow the instructions on the bottle and use water, but for nearly everything else I use isopropyl alcohol.

I dpn't think windex wpuld make a good thinner personally...

a while back, i used Tamiya acrylics exclusively, and they performed wonderfully. saying that, i'd HIGHLY recommend biting the bullet and purchasing the Tamiya thinner. well worth the money. the thinner may smell like rubbing alcohol, but it contains other ingrediants that enhance the perfomance of tamiya paint, such as reducing tip dry and improving levelling properties by extending the drying time. later.

I second that Chris, I even use Tamiya thinner with MM acrylics and others... it seems it really helps the paint go down smooth with less chance of a grainy finish, tip dry etc... I've tried 91% iso and although it works the Tamiya has it beat... for about $6.00 for a 750ml bottle of it ya can't go wrong!! (it's $3.50 for the 60ml bottle so you can see the savings) I use windex to clean my airbrush but haven't tried it as a thinner... not to say it doesn't work...

Thanks all, best to be carefull as lots of money spent on models etc.. will try distiled water as drying time at the air brush tip has to be slow as will glog I guess..Will also try Tamiya acryl thinner to work out the best.I did notice one of my models looks patchy with windex thinner used. a dark german grey color acrylic it was.. catch you soon.
