Product codes appear to be different from what you posted but maybe that's just due to size.
I try to get the chrome buried under as much paint as possible. Also when using the clear I do the first/second coat super light and not too close to the shell. Then 1 or two slightly thicker coats after, giving about 5-10mins between coats for em to air off.
