Is it worth clay barring before polishing?
The paintwork feels smooth so not particularly contaminated, but if I wanna do a real job on tidying up the paintwork, removing swirls and light scratches etc, will I see a benefit from it?
It'll likely damage if not remove the ceramic coat.Can you clay on top of ceramic coating or does it strip the cc off?
Most likely, yeah. I think I let them sit with salt on for too long over the winter unfortunately. They actually usually come up OK after a regular clean, but now the warm and sunny weather is here they've deteriorated more. Or at least that's how it seems.Clearcoat failing on them?
Probably easiest to take them off and give them a decent polish, might bring them up alright or could need re lacquered
