New challenge for me now that my truck has been on the road for 3 years. Several pieces of chrome on my truck have started to rust--specifically the tail-light brackets and the antenna brackets. I purchased these pieces from our usual sources--LMC, Chevy Duty, etc- so I tried not to get poor products via low prices. I am not a big fan of wax and polish on my vehicles, but I do keep them washed, especially the 57. I have never polished or waxed the 57. Is this my problem ??, If not, what is ?
