"Can't Live Without"
This is the best cleaner I have used yet. I just can't paint without it. Pros- I love Tamiya paints and us them when ever I can. There cleaner is the best. I even us it on my Testors paints. Cons- none. It might be a little high in price, but saves a lot in replacing paint brushes, paint guns and parts.

"Works well however very over priced."
greggtrueb (Cincinnati, Ohio)
Don't get me wrong this product works great and can be used with almost every acrylic. However it is way too expensive for what it is. A 2 to 1 ration water to isopropyl alcohol with a mil of acrylic retarder and (optionally) a mil of flow improver per 60oz batch works exactly the same. A lot of the time more retarder has to be added even when using this product anyway so something good to have on hand. I use Windsor and Newton but Hobbylinc usually has Vallejo as well which is essentially the same thing and works well. Pick your favorite flow improver I use Liquitex because I randomly found it in a shop, but any brand will work. 1 bottle each of flow improver and acrylic retarder will last what seems like forever making its unit cost excellent.

"It works"
Matt M.
I use this thinner a lot for airbrushing acrylic paints of course It works good with the Model master acrylics as well as Tamiya paints and I've even thinned down acrylic crafting paints and added a touch of clear coat into the paint mixture for a nice durable finish that don't scratch off I recommend this thinner for airbrushing it gives your paints a nice even smooth surface that you'll want you can't go wrong with this thinner and it don't fumigate the house as bad like rubbing alcohol does no more using that I'll stick with this instead for now on no problems .

"Tamiya acrylic/poly thinner X20A"
While X20A does what it's supposed to do very well, using it for thinning and airbrush cleaning is an expensive proposition. I found a home brew recipe on the internet that is easy to concoct, is much less expensive, and (for me, at least) works just as well. I'll be using the home mix for cleaning my airbrush and the X20A exclusively for thinning, but when I finish this bottle I'll go to the home made mix for both cleaning and as a thinner. PRO: Works very well. CON: Too pricey. I recommend it if you want to Tamiya products exclusively.
