I painted my car JD Blitz Black about a year ago and now I want to actually paint my car a Burgandy color and do away with the flat satin look. I'v heard rumors though that you can't paint over blitz black - I don't see why not though? Is this true? Will I have to sand all this off before I can paint my car?

I plan to do a little body work, prime and paint it without removing all of the old paint (again). I can understand not being able to paint lacquer over it, but I can't see there being a problem with painting enamel over it.

Any help is much appreciated.
