I applied Testors GlossCote Top Coat with the blue label. The new blue label Testors is all that my hobby shop carries now. I think that when Rust-Oleum took over Testors, they changed the labeling. I called Rust-Oleum and was assured that thinning with Lacquer Thinner is still recommended.
I've also been side tracked these last few days so I have not yet applied decals. Hope to get back to it later this week.
