Yes yes on Line-X!! Comes in different colors too.
Last winter I towed home a brand new Haulmark trailer from the factory in UT. Hit a major snowstorm for 100 miles and the gravel on the roads dinged up both the diamond plate and the smooth V -nose. I had the V-nose Line-X'd and replaced the diamond plate. Cost a few bucks but I didn't want a new trailer all dinged up. I found a custom trailer guy in town ( someone who builds snowmobile trailers) and he replaced the diamond plate just like new.
I think LineX is the best bang for the buck
