Ash, I would have to see one in the flesh to be able to comment. As has been suggested, probably better than nothing, and for some people for whom budget IS important, perhaps it is a way forward. As to re-chroming, that is a lottery as to the success, and personally I will always buy NOS if available.
The only PERFECT double cut fender I have ever had (no dents / scrapes, just dulled from 40 years of polishing) was taken to a chrome plater who I have used for years. Unfortunately, and not known to me, the "old guy" who did the polishing had retired. The youngster who took over can polish, as long as the item is made of armour plate! That perfect fender is now so thin you could use it for razor blades - the chrome at the front edge is thicker than the remaining metal. As we all know, the money charged for the re-finish is not the issue, cos these things are too damn rare (and costly to buy via Ebay) to have ruined during plating. Just can't justify a Yamiya repro right now.
Good luck with however you decide to proceed. - Chris R
