Guess I should have added all this to my original post, lol... I typed out the post really quickly and forgot all the details. The dye is called "ColorBond" and is sold at WalMart actually. $7 a bottle, one bottle is supposed to cover 7sq ft, but it seems to cover more. (Yeah I cant believe I bought something from walmart, but i figured that $7 at walmart would be like a $14 equivalent at AutoZone lol) I went back for another can and they were out, so I went to another walmart... they had an older package that seemed the same called "Molecubond" which I tried hoping it was the same... it definately is the exact same, just older packaging. It only comes in like black, gray, and a few other common interior colors from what I saw... not a wide variety of colors at all. It says it can completely change the color of the interior... example shown was bright red to black.
