Hey All,
I am using the New formula copy cad kit. I am restoring an old Motorcycle and am looking to get a pure CAD finish, I do not want a bright Zinc finish.
My problem is that no matter what part I plate I get water marks on the part when it is dry. The finish looks great at first until it has dried and the marks are left.
The next problem is, after the part has been left untouched for a day after plating once handled it begins to start to oxides. My findings are that you must chromate or seal the part to keep the raw zinc from prematurely oxidizing. I have read that WD40 will seal the part, but how long will WD40 last in protecting the part when it is out in the elements while on a motorcycle? Is there other options for sealing the part to get the best protection for weather? Do they make clear chromate?
Here is the thread that talks about the WD40
Fresh copy cad system leaving white swirls
MY Setup
Bead blast with glass beads
blow off with air gun
SP Degreaser for ~2 min
Distilled water rinse from a squeeze bottle
10% Muriatic Acid dip ~1-2min
Distilled water rinse from a squeeze bottle
Plate in Copy Cad Solution w/o brightner @ 110-120F For 20min
(I am setting my current to .14amps/in^2)
Distilled water rinse from a squeeze bottle
Hang for at least 12 hours before touching
I have also used the air gun to dry the parts after the last rinse, but still get the water marks when dried.
Then after it has sat for a day or more and is then handled, it will rapidly oxidize, so I am looking to know what sealer to use for an outdoor application.
Thanks for your help,
Josh
