I just bought a 2013 Jeep Wrangler Sport, what would youto clean/wax the plastic wheel covers, bumpers, etc. i have a black clear coat, what auto wax is suggested.

Go to a forum like www.detailingbliss.com/forum/detailers-domain/ - There's endless discussions on the proper cleaning and waxing. It all depends on how much you are willing to do or pay. Many people have paint protection film applied on the bumper, hood and front fenders to prevent chips. YouTube would be another good source of detailing information.

It depends on climate and road conditions. If there is allot of road salt used where you live, I would recommend a hard wax like turtle wax (It will also last longer) but if you live in a more moderate area where less road salt is used, I would recommend you use a softer wax which has more luster but won't last as long.

do you have painted or black flares?
