I recently purchased McKees 37 Fast Metal Polish to use on the bumpers of my Ram 2500. I seen a few people mention that it worked great, and for the price I wanted to give it a shot. I was definitely not disappointed and it was very simple to use, even by hand. I first gave the bumpers a quick cleaning, then I used a microfiber pad that one would typically use for applying waxes, and kind of blotted it on the bumpers every so often just so I could keep going. I also used it on the chrome covered plastic on the grill just to try it out and had good results for the state that the grill was in. Took maybe half an hour to do both bumpers and grill. Would recommend trying this product! Will be trying out more of McKees products in the future.
Pros:Easy to use, smells good
Cons:large bumpers may tire your arm out haha
