    Looking for some help with what to use on my bonnet ! the paint is sapphire black metallic and its an 06 Z4 , I have a DA and have detailed most of the car using scholl 17+ and meguiars ultra cut compound 105 with geart effect on the rest of the car:D but I cant get a decent finish on the bonnet :(
    17+ has impoved it a little as did meguiars paint rejuvenator but it still has a milky look to it any ideas !!:) thanks

    Has the bonnet been refinished and lacquered? A poor prep could cause condensation or wet base below the lacquer, which would require a strip and repainting. Hopefully it's not and just needs a bit more elbow.

    Difficult to say without seeing it. By milky do you mean a dull, washed out finish? Poor gloss & lacking decent reflections?
    It could be numerous things, have you owned the car from new? If not it may have had the bonnet resprayed at some point in the past & has either been prepped or finished poorly.

    You could try taping off a workable section & using the most aggressive combination of pad/polish set about doing 2 or 3 sets (leaving a few minutes between sets), refine as I presume you've done with the rest of the car & see if it results in an improved finish?! If so then you know what is required. If not then the next step would be for someone to try a more aggressive approach with a rotary/wool pad and/or some wet sanding. Last resort would be a repaint.

    Yes, that pic doesn't give anything away.
    A better pic would be with the sun on it, stood at the front of the car with the camera pointing directly down on the bonnet.

    Ok been doing a bit of Googling and some people think the cloudy ness is caused by degeneration of the clear coat ,because of heat from the engine ?! And shows up more on black cars !

    Hmm! I'm not convinced, maybe if its been repainted at some point previously & it's not been the best of jobs that may be plausible. OE factory paint will not degrade as you've said.
    Compared to a big Italian v12 a Zed engine barely gets warm ;)

    I'd go for a repaint causing it!
