Default PVD coating vs Chrome: Any feedback?

Anyone have any reviews on the new PVD chrome coatings vs the good old fashioned hardcoat chrome! The non-peeling is a + but how about the shine? scratch resistance etc?
Thanks!

It all depends are where they are done and the condition of the sputtering system it is done in.

The Physical vapor deposition process uses a powder coat, PVD Cr, then PVD NiCr, and the last step is a powder coat.

If it is done correctly the adhesion will be fine. But, as some of the forum members here can tell you, if done incorrectly (Vacuum leaks in the sputtering system or gas lines, incorrect prep, dirty environment) it will have delamination issues.

We just threw out our last sample wheel, so I do not have any wheels left to take pictures of. The shine was good but I would think that the bath type Chrome process would be a higher shine. (No clear coat on the final finish.)

Since it is clear coat (powder coat) you can remove some scratches if needed.

I believe chrome to still be more durable but needs care just like any wheel type. Chrome often pits when caustic brake dust and other damaging contaminents are allowed to sit on wheel for extended time etching the surface. A good cleaner, and chrome polish often keep them shiny and new.

Since PVD coatings are similar to a powdercoating/clearcoated wheel you likely need to use extra care in wheel cleaning products, polishing, and protecting. I am guessing that chipping "could" be a possibility and likely leaving nasty stuff on the surface could damage it also. The biggest benefit is likely most can handle them like a traditional painted wheel.
