New member here...at least as far as owning a Yukon....but not new to detailing. There are lots of good trim protectants out there....some short term...some longer term. Trim on the new Yukon has been protected with CQuartz Dlux, as have the wheels. I just used 303 Graphene on it....mostly as a test. Vehicle got a full decon, both mechanical and chemical, which it needed. Had to do some correction in places....some nice dealer installed swirls and some water spots. 303 Graphene is a little oily and stinky, but came off easy enough. Gloss is nice, but slickness just not there. Nice part about 303 Graphene is that it has no cure time, so I was able to top it right away with Ethos Defy.....slickness issue solved. Gonna put some pics in the gallery so I can embed them in posts.
