Detailing / Re: water spots spotted on front hood
« Last post by willni on 06 April 2026, 20:46 »Although what SRGTD has said is correct, it's also not really a thing anymore due to paintwork being baked to harden, rather than to just dry and so it's unlikely to be the root cause unless repaired by a bodyshop without baking equipment.
There's plenty of folk getting PPF put on their cars immediately after a repair being carried out, further depending on the ceramic coating, the majority are gas permeable so can continue to let gasses out, although still advisable to let it sit for a week or so before working on the paintwork.
You mention rewaxxing the area, so I'm going to assume that you used a ceramic infused wax instead of a ceramic coating.
They're likely just hard bits of waterspots (limescale), and hand polishing may not have been aggressive enough (Some of them are hard enough to remove even with a machine polisher!), let me know what products / pad you used to hand polish to help further.
Koch Chemie FSE is a quick detailer with waterspot remover in it as well, it can help and leave a lovely finish. But if you provide us more information we can help better before saying to throw money at the issue.
