I have a new Ram Laramie and the chrome on the front is extensive. I put a coat of Blackfire Wet Diamond on it but wondering the best protection for this material - I guess it is metal/chrome? Would Wheel Wax or some other product be better? My past vehicles would get metal etching over time from the road salt/mag chloride, etc. even when I tried to do a quick metal wash in the garage in the winter after driving on messy roads. I also use Blackfire detailer after washing. Other suggestions? Thanks
