^ Good question. Some people say yes, some people say no. A lot of people like to top it with other Opti products and claim success. I plan to possibly wash it this weekend and hit it with some FK425 (quick detailer that is super slick) and see if it makes a difference. I also plan to try a few different waxes and sealants so I will share my personal results. From what I have read, if you do top with a wax to help enhance the gloss, some waxes have a hard time sticking and do not last as long as they would when bonded to normal paint but do indeed make it glossy. OC is pretty shinny IMO so the need to top it is kind of up in the air on my car since it is Silver but I would still like to know for future reference. Maybe on a black or darker color car it would be more desirable.
