I was always under the opposite impression, that people who do use PPF and ceramic coat do it PPF first. Hmm.thank you. odd i have done all my cars with ceramic and did clear bra and i know many guys also do same and never had a issue.
only way to remove it is to buff out the entire paint and start all over. which would make no sense.
there is also no need to do ceramic over clear bra as you dont need to protect it like you would with paint just be wasting your money
