Just done a bare metal respray on my car in cellulose and am slowly coming round to thinking that I have either made a bad choice of colour or that it was a poor mix. Either way I'm not sure I like it!! If I were to change the colour I would obviously not take it back to bare metal again but would I need to prime it again or could I just paint straight onto the (I suppose wet flatted) topcoat? Its only been painted a week and not been polished up or anything. Thanks for any help/suggestions.
