The boy hath already done - surprised you weren't blown away by it though Rich - Black hole is amazing stuff.
i could still see swirls in the paint, which made me think i was using it wrong, had the DA set to about 2 and wokred it in to the paint, left it to haze, then buffed off, but it didn't seem to do much don't know if i should have worked worked it in more or what got plenty of time to play with it. i'll have another go next clean.
Blackhole is like britemax #4 isnt it? If so its just fillers so you will still see the swirls but just less.
