I have recently had my magenta saff painted, but unfortunately the engine has let go so its in my garage having a rebuild. Last week whilst fitting the rebuilt engine back in a noticed that the paint has gone quite dull, it has sort of like a haze on it when the light catches it. Anyone any ideas why and how to rectify it. It has been suggested that it just needs another good mopping. I have tryed a waxing but this doesn't to improve it much.

Also what the best polish to use on magenta paintwork
Cheers all
