Is there such a thing as PVD touch up?

[CISO1969]

Just got a Pam 195 in PVD and am worried about the finish getting scraped. Is there such a thing as PVD touch up paint or a touch up pen?

I was thinking fireplace black paint might work if needed?

Touch up?? Light scratches around lug holes, screws, buckles a sharpie will do the trick. The sharpie worked for me. 8)
8) 8) 8) DOC

I thought of a sharpie--but it leaves a sheen and is noticeable. I also have used something called MNU on my insignia when I was in the guard--but that leaves a glossy finish too.

I'm thinking a very flat black paint should do it but wanted to see what was available commercially first.

Has anyone found a good PVD touch up yet?

True PVD cannot be touched up. It has to be completely removed and reapplied.

Black oxide however, can be reapplied without being removed.

IMO, nothing will look the same.

Please consider the sharpie again. If you put it on, leave it for a fraction of a second, and then smudge it with your finger it will not be too shiny. Try it several times. I swear it will work pretty good.

I want to know also, maybe a new recoating?

Almost out of the question for the average person. First, you would have to find a source. Second, having one watch coated will cost you A LOT of dough. :?

 

[Sylar]

If a watch is worn a few marks here and there would give the watch more character than keeping it brand spanking new.. having it completely recoated is the best and only option but like jb said hard to source and then expensive. Might as well get another watch at that point.

I am quite positive that black oxide cannot get performed either on stainless steel or PVD. Black oxide needs oxidable matter, and neither stainless steel nor PVD can get oxided.

Caswell Inc is selling a stainless steel blackener (Stainless Steel Blackener 370, look near the page bottom of their black oxide kit page):
http://www.caswellplating.com/kits/black.htm#stainless
but be warned it gives a gray (not black) finish, and results are variable depending on the quality of your steel. Been there, done that.
It might work in order to just retouch some small scratch though. At least, your scratches might look dark gray, not shining steel...

Black oxide can be applied to stainless steel.

I think you misunderstood. I was not trying to say that black oxide should be applied to the PVD coating. Although, I do not see why you could not apply black oxide to the case with the PVD on it and have the BO fill in the gaps. However, there would be a difference in color.

Although I have never owned a PVD PAM, so I can’t prove my theory, I have serious doubts whether or not the “PVDâ€

Black oxide can be applied to stainless steel.

Did you try it first hand?
In this case, please let me know where you got your black oxide solution/kit/process.

Because black oxide, as its name tells, is an oxidation process, while neither SS nor PVD are oxidable.
If they were oxidable, they would soon or later show stain on their surface.
That is also why Casewll Inc provides a Black Oxide Kit for [non-stainless] steel, and a different product (the abovesaid Stainless Steel Blackener) for stainless steel.

I do not have to try it first hand. I have a black oxide vendor that performs this service for me.

Although this is NOT my vendor, this is a company that I sure would be happy to black oxide SS for you.

I have several PVD PAMs and I had some tests and discussions on them.
I too was very dubious about it, but my conclusion was that it is real PVD,

Under what scientific conditions did you perform the analysis of the coatings you tested?

and there is no other way to make SS black (apart from horrible and obvious paint coats).

This has been disproved above, but I would be happy to provide you with a sample.

The bad, shining look of the rep PVD is due to the fact that PVD is applied on brushed SS with no beadblasting performed before applying the PVD coating.

I agree with this statement. PVD will mimic the finish of the substrate to which it is applied. However, there is an obvious difference in the feel between the two when they are side by side.

Just in case anyone is wondering about my background, I am the engineering manager for a large manufacturing company. The company I work for mainly produces components for the sheet metal stamping and mould industries. PVD, CVD, TD, black oxide, and numerous other coating run across my desk everyday.

Thanks for the link, I am very interested. I quickly cheched it but I'll check it more thoroughtfully as soon as I'll be back from a short vacation that I am leaving for today.

Under what scientific conditions did you perform the analysis of the coatings you tested?

I did not say analysis but tests. They were just about light reflection at standard temperature (no more than a digital photometer), microscopic texture at 10x and 30x, and scratch resistance vs a sapphire pin mounted on a weight and left falling from a same height. Surely nothing sophisticated.
The results between 'rep' PVD and 'true' PVD were comparable, and different from the results on stainless steel treated with the Stainless Steel Blackener. I did not get comparations with black oxided stainless steel though, as I have not been able to black oxide stainless steel.

And you, on what scientific evidence do you think that 'rep' PVD is not PVD?

This has been disproved above, but I would be happy to provide you with a sample.

Thanks, I'll be even more happy to get that sample.

 

[jb]

And you, on what scientific evidence do you think that 'rep' PVD is not PVD?

None, other than a visual inspection of a friends watch, YET. However, when I do, and it will be soon, I will send it to my PVD vendor for verification.

Thanks, I'll be even more happy to get that sample.

PM me your shipping address.
