Picus:
The ColorFill is regular paint indeed... all you do is send your color code (factory paint #) to them and they mix it up. I know it dries in like 5 secs when you rub it on your car and has the consistency/feel of the real automotive paint (it's thick like the kinda you get in the little bottles). All I know is that is matches perfectly to my car's paint and actually blends in better than Langka (which tends to make the color of the paint lighter for some reason).
I think the Blob Doctor would work fine with the OEM paint bottles, which is what I'm getting next to try. My Langka kit (no offence to anyone) doesn't work very well at all, and it was $30 Cdn. more for it too
