Thanks for the info... Only other question I have is it doesn't say anything about prep work... Do you have to use a light sand paper an rough up the back glass or just tape it off an spray
I have never sanded the glass before painting. I just clean the glass very well, tape it off and paint. I haven't had any issues this way. I usually use a flat black spray paint.
Yeah, spray paint, don't rough it. Just keep putting on layers until you get good coverage. It'll look like crap from the back (runs and ridges and what not) but from the front it will look perfect.
