Acrylic/Poly Thinner X20A 8.5 oz

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.
