PPF is the rubbery protective adhesive-backed film (PPF stands for paint protection film) that gets wrapped onto the vehicle. "Ceramic" is a liquid that gets applied onto the paint (or the PPF) like a sealant product to make dirt easier to remove, provide better beading and shine etc. Ceramic coating doesn't provide any physical protection against rock chips, dings or scratches.Love it! Very sharp! Do most people wrap in ceramic to protect or just hard core off wheelers?
