Rob, thanks for the comments! Testors has two different lines of stuff...there's the "regular" line under the Testors label that just has Glosscote and Dullcote. Then there's the Model Master line which has three types, Gloss, Semi-gloss (satin), and Lusterless Flat. I've always used the Lusterless Flat and it really does make everything dead flat...so I've used it over the standard Dullcote as many years ago when I used it I would sometimes get a slight sheen still present vs. the Lusterless Flat. I buy the stuff in the spray can for ease of use vs. mixing my own and applying via airbrush. That's all I can say about it, HTH!
