MC260 and 270 is not available anymore in many states, the new VOC compliant Omni clear is MC262. Anyway, check out this thread I did with my firebird, it talks about clear coating, and all stages of prep through polishing. Hope it helps. I cannot recommend reducing paints beyond what the manufacture recommends, I don't agree with it, but to each their own.
