Yeah but MM (Testors) has multiple thinners and then 'AB cleaner' too. Once upon a time the AB cleaner was some "diluted and cheap" form of thinner that would clean an AB but when mixed with enamels caused them to dry painfully slow. They did change that formula though and you don't see that excat stuff anymore but be careful if you have some old stock, it's just not great for thinning.
But MM (Testors) has enamel and lacquer "thinners" on the shelf. The lacquer comes in a black can and I don't recall the number on it but it says lacquer and that's what you want for the lacquer clearcoats. But, they also have enamel gloss clear and therefore you'd need the enamel can of thinner, in a blue can marked as 'Airbrush Thinner' or in a red can marked as 'Universal Enamel Thinner'. The cans I refer to are all 8 fluid ounces. The bottle of lacquer thinner is #28016 for 1/2 fl oz.
But are all lacquer thinners created equal- quick answer, no. They have specialty thinners that are guaged toward temperature ranges to allow the paint a chance to level in hot weather or dry quicker in cold weather and not be so prone to runs. But that's when you buy in bulk at an Auto Paint supplier so that leaves most people shopping at the hardware store or WallyMart. Well, it is lacquer thinner but honestly I save that stuff to clean my AB since I'm not going to risk my paint job to something that doesn't behave as I'm accustomed to. But on the other hand you can certainly try a test panel and if it goes on well and then cures- what's the problem?
Let's see, 1/8 fl oz bottle MM appx 2.48
8 oz can MM appx 6.99
32 oz lacquer thinner from K-mart appx 4.99
Hmmm?
