u got scuff marks in your new car ? anyways I have not needed anything more than opc to clean my interior, or other apc's . they do make stand alone interior cleaners and protectants from many of the major brands . some interior products are a combo, cleans and protects . I thought 1Z made a product that was good on scuff marks ? the magic eraser works too . as far as a shiny protectant ? on my vehicles I use a interior sealant . ultima interior guard or Wolfgang cockpit . I actually like the Wolfgang better . I wouldn't say either of these are shiny though , but and edge to Wolfgang. other fav I have and use are , carpro perl and Meg's 40, dp interior cleaner and interior surface protectant . if u want shiny , I suggest perl as u can mix that to your liking or you can always go for Armour All . JK !
