Not quite as "midnight" dark as Testors Dark Sea Blue - but it is as fine, and perfect-drying a spraypaint as Tamiya (or anyone, for that matter) ever made. So good, in fact, that I use it as the #1 backup whenever I run out of their TS-24 Purple, for inspecting resin pieces, as shown for the latest FBM nosecone prototype, at bottom-right. (What's that? Oh yeah, buddy - I been working on the FBM parts, and they are comin' along - you betcha!)
I don't know if Tamiya has a darker gloss blue, but I'll bet they do - and if your hobbyshop isn't carrying the above, then they are definitely not carrying everything that's available; get that cheap-a** store owner to crack open his catalogue for you, and look-see what-all's really in there! (And tell him I still have four Zhengdefu CGs that I got for $3 apiece! )
You are so right about the Testors - I won't even use their Camouflage Gray anymore; it sprays too coarse - like spray-concrete - and my parts are too detailed anymore to cope with that glop. What I'll do now - if I have to - is catch it in a basin, thin it with mineral spirits and then re-spray it. Which kind of defeats the whole purpose of a spray can, eh? Fortunately, their Gull Gray is not quite as bad, and is a better match for modern Haze Gray anyway.
BTW, Tamiya's spray flat Haze Gray, being very dark, is a near-perfect improvement over Testors spray flat Intermediate Blue. Which is one of Testors' better ones, but still doesn't hold a candle to (anything of) Tamiya's.
In any case, you did a helluva job on that little HellCat, Donny!
