does one wax over chrystal guard or is CG a replacement

04 6mtC, DG - possibly most babied G on the board.

 

CG replaces wax. Higher melting point and hardness than any carnuba-based products, but it won't fill scratches. Make sure you clean, claybar, and polish your car before you throw on CG the first time. If you do it right and do a minor touch-up of CG every month or so, you'll never have to do it again. Minor CG touch-ups are pretty simple... spray bottle of water, spray bottle of CG, and just go panel to panel with a spray or two and a quick wipe.
