Stephan does good work, You can see some exaples of his work here:

https://board.moparts.org/ubbthreads/ubbt...tml#Post2013296

I've had three done. One by Jules. One by concourse creation( Jerry Smitch) I think that his name. The last I had Bill Merholz do. I think it is the most correct. It is not shinny like the rest. Most polish the barrel on the motor to get it real smooth so the cad plating looks shinny. That takes the detail from the barrel and almost polishes away the numbers. Bill communicates very well and will send you pictures of your motor. He is the most expensive but it is the most correct. I can post some picture later if you want.

I didn't know dings on the wiper housing was correct. I talked to Bill and was asking him about restoring mine but he insisted I take a date coded wiper motor already done that had a ding in it. Why would I trade my dentless wiper motor in for one that has a dent lol?Why would you even restore one like that and try to pass it on to somebody??? Needless to say Stephan did mine and it was flawless and I can't think of anyone else who I would send one to. He also did my Headlight motor, it was also sweet!

I understand completely. He sent me a picture of one that had a ding on it and it was very dull. He wanted to sell it to me and take mine in trade. I passed as well. I sent mine in and he plated it with a slight brightness to it. It did not remove the detail on the part numbers. After I got mine back, I compaired the two. On his you can clearly see the deep stamping of the part numbers and date codes. The other two I have are smooth, shinny and you can barely see the part number. All of my other original core motors are stamped very deep. All I'm saying is that shinny-like-a-diamond-in-goats-butt is not an OEM finish.

Check the inside of an NOS dull motor and it will most likely be shiney

If the above wiper motor came out of that box, then why are the dates codes on the motor and box different? The wiper motor I had restored by Bill looks more like that one than the two I have had restored at other places. They are so shinny, that they glow. The biggest difference I see in my restored motors from my OEM and the ones Bill did is that the numbers are very shallow. Especially the numbers in the middle. They are almost polished flush. I'll try to post my pictures but I may not have time today and I'm going out of town for the weekend. I'm not trying to start a pissing contest here, just pointing out some things I have observed in the work I have had done.

I'd be interested to see the finish on the inside of a well preserved motor, but don't believe it would have ever matched completely with the outside due to shielding from the current during the plating process When parts are plated the inside surface will almost always be less bright that the exterior. The way to try and avoid this would be to use a conforming anode, more costly and time consuming, a method I highly doubt Chrysler would have imposed as a requirement.

As for brightness, there are several factors that play into this, as someone pointed out, the quality of the substraight prior to plating plays a factor and since these were new at the time of build I suspect the finish pretty nice but certainly not polished to remove small imperfections in the surface.

Another factor affecting surface finish is the use of brightens within the plating bath. Brighteners act as a leveler to the material being deposited, the smoother the deposit the more shine to the finished product. Brighteners are not all created equal, some performing better than others and the amount used (and maintained) in the bath plays a factor as well.

While I too have my own opinion of level of correctness I can say theres a scale or range that should be considered plausible as I'm sure that if able to inspect a few original motors done in the day, variation could be seen.
