Culture in the neon shop? Anyway, try Dixie Neon (Charlotte,NC) 704-357-1711. They will dropship blockout any where. Yes the stuff works well IF you stir the shit out of it. I know someone who built a pump / stirrer into his dip tank and swears it works great. The people who make this blockout are the same ones who make that glass tinting paint that you sometimes see on beer signs instead of real ruby, emerald, gold, or bromo. MC
