Notwithstanding the power coated ones you found
may be hiding damage that's not been properly repaired and that the tyres may be inferior, I think diamond cut rims are a liability, period. They will eventually need repairing anyway as the clear lacquer will eventually fail (if only from stone damage) causing 'white worms'/alloy corrosion.
This doesn't mean to say you couldn't decide to have diamond cut ones 100% power coated at that point though (as I did for mine
only to once and for all avoid further hassle with diamond cut surfaces). 100% power coating should be
much more robust (the paint covering is thicker than clear lacquer on diamond cut surfaces and edges for a start) and also they should be easier to repair/touch-up at home should they get damaged by light curbing or just stone chips. So, I would say just think about how the wheels might look when eventually 100% powder coated. That may influence your choice of rim to start with.
Also bear in mind that repair of diamond cut surface damage can only be done my cutting back the surface on a lathe (with a diamond based cutter). And that can only be done two or 3 times at best over the life of the rim or too much material gets removed and the profile/look of the wheel changes, let alone its structural integrity. At that point the only choice is to scrap the wheels or completely powder coat them anyway!
You can't tell from the photo if the diamond cut ones you've found have already been repaired/re-cut, maybe more than once, already...
So guys, after owning the car for 2 years I have slightly scuffed the nearside front wheel and Im so annoyed. The wheels already have had some sort of refurb and it wasnt the best job. To be honest the damage is quite lite but still annoying. Im still deciding wether to get it sorted. So I...
