I gave up on plating before even starting and cheated. Duplicolor works just as good and is waxable
Is there a Duplicolor spray can that produces an end result looking like yellow zinc? A long time ago I bought a set of 4 spray cans with which you could mimic the yellow zinc appearance but it just didn't
Seems to me to be a slippery slope with no finishing line! I'll be the first to point out the bits that haven't been done!
Some things I clean , steel wool and clear coat. Or paint. Others , well like a leather jacket , patina rocks!
Then there are people try to save money but end up spending more and missing out on more pleasurable life activities Power to them!http://www.xenonz31.com/Cadpaint.html
What's the best way to try and preserve factory coatings? I have 31K miles 91 GT and the coatings ( cadmium?) still look fresh. How do you try to minimize loosing the factory finish?
If you want to preserve for added value sometime down the road and don't mind an oil coating, use 'Fluid Film'. It works wonders in preserving metal. Easy to apply and will wash off
down the road if you need them back to new. Even if the bulk of the coating is washed away it maintains it's corrosion inhibiting properties.
What Bertrand said, wherever practical. Best solution is to avoid exposure to low-pH cleaners, and of course no salt exposure. And --NO-- abrasives while cleaning parts, not even the scotch-brite scrubby songe. That -slows- the degradation. Ultimately the cad will deteriorate, as it sacrifices itself to save the steel bits it's coating. The clear-coat stops that.
The second batch did not hold as well as the first. Why?
Be it painting, plating or whatever, everything is in the preparation work which is why I prefer to do that portion of the work myself.
Here is one of many brackets I took in for yellow zinc plating after I stripped the old finish off the original bracket.
The original Porsche finish after 19 years...
After dipping the bracket in muriatic acid to remove the old yellow zinc plating for a like-new down-to-the-metal finish...
The fresh air intake system bracket after having it and all other engine and transmission brackets and mounts yellow-zinc re-plated...
A few words about using muriatic acid to strip the original plating off the metal brackets and mounts...
wear a mask with filters for acid gas.
perform all work outside with a slight breeze and stand upwind of the work.
wear protective eye-ware.
wear protective gloves and clothing.
Brackets that looked heavily corroded such as the forward transmission bracket on my car looked like new after dipping the part in the muriatc acid and working it with a 1" paint brush. What looked like heavy pitting was actually the original yellow zinc plating that turned into a coarse finish, almost barnacle-like. (zinc is a sacrificial metal)
After drying the parts, I place them in zip-lock bags to keep them from flash rusting.
