Peugeot frame chrome issue

Anyone know why Peugeot put a clearcoat over the chrome on the forks and chain/seat stays? Everyone I have had the chrome looks terrible until you strip the clearcoat of then polish it back. Did they do it to protect the chrome from chipping? or some other reason.

Below is a before and after shot.

cdaniels -

The Peugeot forks I have restored that were half-chromed did not have the upper fork blades steel polished before chroming was done. That would allow better paint grip when the fork was painted and decaled. Next, the whole thing was clear coated on both paint and the lower, chromed fork legs. It would save a production step in masking and, in the short term, keep the fork chrome clean and shiny. In the long term, not so much.

That sounds right. I just striped my whole frame and the chrome on the stays only goes about 2-3 inches past the paiint line.

Thanks

Clear coat over chrome is a quite common protection.

Though the factory applied clear coat over polished chrome did not stand up well, it did a wonderful job of protecting polished chrome plated surfaces. The issue, of course, it that the clear did not adhere well to the very smooth surface of the plated surface. The adhesion was so poor that, as often as not, one can scrape it off with one's fingernail.

For my money, I decided to clear coat the polished chrome surfaces on this late fifties Rabeneick 120d. I have never bothered to do this before the Rab's restoration. I know that the clear will not adhere well, but the bike will see the most careful of use, suggesting to me that it will remain in place and ****** oxidation for a long time. Fingers crossed...

Motobecane Clear Coated Chrome Too

Back in the early 70's Motobecane clear coated the chrome plated forks and stays too.

Here's my 1972 Motobecane Le Champion

Fork before and after - the chrome was in perfect shape.




Over years in storage, the clear coat on the paint went south too.



The clear coat on the chrome on my 1967 Peugeot is starting to flake a little too... But after 50+ years!

All the particulars above explain the what, and confirm correctly that, yes, there was clearcoat. I don't know why, but I've seen a few people on BF try to say clearcoat wasn't used on bikes prior to the 1980s, but I've seen clearcoating done as early as the 60s for sure.

As for removal and protection after, if that's interesting, and you don't want to mess w/chemical. Whatever you do, DO NOT use steel wool. Get 0000 bronze wool, and work with light-to-medium pressure. If you plan to re-clear, be sure to follow proper prep with a tack cloth and cleaning solvent. If you don't plan to re-clear the chrome, you'll want to polish and seal it. Turtle Wax makes a good chrome polish & rust remover product that's quite good, you'll want and/or need to re-apply at least once a year, or every few months if you ride in wet areas or live in a salty-humid environment.

Some folks I know who are ultra-anal-retentive (nothing wrong with that) will follow-up with multiple coats of wax the first go-round.

Oh - and not bashing on anyone using steel wool. It's just an inferior and invasive product when it comes to restoration of steel stuff. I can list all the reasons why but feel like a broken record sometimes restating the same thing over and over.
