I know some meguiars products are " paint safe".
I am wondering what prep needs to be done to clean for painting if paint safe products have been used.
I am familiar with using strong detregent like Dawn soaps and purple power to strip oil and grease and wax before bodywork.

Also wondering what needs to be done to remove NXT for bodywork.
Best way to wash and remove for bodywork/paintwork?
any special cleaners or soaps that work best? is it silicone based?

I am also looking to change to and try the ceramic wax. Any differences or different cleaning products to remove ceramic wax?
same questions: best ways to remove to do paintwork?
I believe the ceramic is silicone dioxide? SiO2? which is differenet than liquid silicone based waxes?
