I had the same experience from Losi. I bought some rear mud guards (off eBay) and one of them did not have the protective film on one side. Being a clear guard it showed up all the scuff marks, from moving around inside the packaging. Now normally I wouldn't of worried about it as I would of got them all muddied up and scratched soon or later, but at the time it was a shelf queen while I was buying parts for the build and wanted it to look the part while I was working on her. I emailed Losi and added a photo, told them I purchased from an eBay trader who stocked all Losi parts, they sent the new part out ASAP and I had it in a week or so. They kept me informed and shipped when they said they would, I say very good CS
