yes you can paint the outside, walmart in the crafts section has what is called 'Stained glass paint' in red that dries transparent. After several coats of that, just apply a few coats of clear coat and you're done.
yeah, don't buy teh japanese stuff for $30, thats a major rip off. Get some stained glass spray paint by krylon and then some duplicolor automotive clear coat to put over that. It'll give you a nice smooth and shiny surface.
INSANE8- that can happen. We did a job like this to his del sol tail lights. It doesn't look bad at all tho. It looks better if you spray the entire tail light, not just the blinker lense. Then it'll give a uniform shade regardless of the orange behind the one lense.
yea mine looks tinted too. but i did it like 2 yrs ago. i put several clear coats...one too many i think, but now i noticed it started cracking. wonder what it is?? and you can notice the clear coat, its not smooth(but maybe its cuz i put too much) but its shiny as hell though!!
