A good tip tho is that if you want the finished product to be shiny like factory gold cad plating, then you should polish the parts before handing then over. A dull finish on the metal before plating means it'll be dull yellow after.
thanks i would not think of that. definitely good to know.
The plating is essentially transparent, so it's a bit like spraying a yellow clearcoat over the part, so you do have to shine them up with some scotchbrite or actual metal polish, which means you have to remove any corrosion with a wire brush first.
It's not like chrome, where relatively speaking, a thick layer goes on top of the metal.
No Kev, you are eating a duck fetus.
