There was a guy over on hotrodders.com that was messing around with a homemade system. He built his own dual gun spray gun with ss internals
He used silver nitrate for the mirror, aka chrome solution.

he was getting fairly well along with the process that last I read. If I remember correctly he was trying to find a clear coat that would not dull the chrome look and at the same time keep the uv's from turning the shiny chrome look into a dull silver look.

Bottom line, it isn't chrome and is only as durable as the clear coat .

That looks like the Alsa system. We have had them do parts at work and they don't look that good. They don't show the clearcoated parts in the video. I think that is the difference, the clearcoat dulls the chrome finish.

If we need to chrome something that is not metal we vacuum metalize it.

Edit: I talked to someone who said the Alsa system actually does work well. Very inexpensive also for the DIY setup:

On my late TT column, I have a real '77? chrome horn button, but the Tele lever/ring is not, just painted, the paint fades in the Florida sun....

and the black vette emblem in the middle is cracked on the surface anyway....

what can be done??

That's a pretty good analogy.

A process I have an interest in is vacuum metallization. I've had a couple of contacts with people who do this. Plastic parts are commonly now vacuum metallized. Many of the "chrome bumpers" on modern cars/trucks are actually plastic parts that have been chrome vacuum metallized plated. These plastic plated parts look just like metal chrome plated parts. Consider the chrome license plate holders for 1968 to 1973 Corvettes. You can't really get them perfectly re-chromed since the plating chrome won't get into the nooks and crannies of the assembly. Being exposed to exhaust fumes, the repro parts don't last in perfect form too long before they start to corrode. Over the lifetime of my 68, I've bought a bunch of these things.

Of the two people, I've contacted, they've offered to metallic vacuum deposit chrome on my metallic parts. (These 69 to 73 license plate holders) I have to get them stripped first. I just haven't the priority to now work this issue. Vacuum depositation is generally not as robust as electrolytic plating, but the vacuum process will get chrome into small narrow areas that electroplating won't.

Also, the rear bumpers of 68 to 73's. When you re-chrome them, there's no/scarce chrome in the interior of the "elbows." These areas quickly corrode. (Actually I put some aluminum or "chrome" paint into these areas - can't normally be seen.) I also wonder if the rear bumpers of these cars are also subjects for vacuum metallization. For a garaged car, this might be a good process.

Vacuum metalization is vapor deposited aluminum that requires a clear coat for any kind of long term durability, specially exposed to weather. Most chrome plastic these days is real chrome over ABS plastic.

The license chrome problem is because those parts are rack plated without a proper shaped rack to direct the chrome into those corners.

I just got a roll of the Alsa chrome wrap to try on my fathers bumper... Looks pretty damn close to real chrome!
Heres a piece next to my bumper:


And another test piece on my fathers bumper to see how it shrinks and stretches (color os a bit off from the camera):
