In college I painted an accurate starmap on my dorm-room ceiling, and it glowed fantastic... was a great excuse many a time to lay on the bed to be looking up, and turn the lights out.
So I wanted such a kick-ass starmap on my home theater ceiling... and spent the whole day mapping the stars onto the ceiling... and then made it all dark to "check it mother fuckers" and it was.... dark. Couldn't see one damn star... although I could see the blob of paint I musta dripped on the carpet. Damn it. A whole day's work down the tubes.
Hitting the online google-fu, I've learned there is a difference between zinc-based glow in the dark shit, which is stable in water, cheap, and thus used by 99% of all "glow" products, but which also sucks ass.
Then there are strontium based glow products, which are not stable in water-based products, expensive, and thus not used except in about 1% of of "glow" products, but which kicks ass. By "expensive" I mean like $10 for a half-ounce. Yeah, that won't break my budget in tiny "star painting" quantities.
I must have gotten lucky with the glow product I used in college (did I just pun that), because I didn't otherwise get so lucky with my recent glow purchase. Clearly must be that zinc-based crap.
More to follow when my new purchase of strontium-based glwo paint arrives.
