1. Black Chrome Plating Parts are not glossy enough?
The black chrome plating parts that apply to RoHS, are not glossy comparing to the ordinary chrome. When you received your black chrome parts, rub them to remove the oil and polish a little bit with a soft cloth within 4 weeks.
If you miss 4 weeks and the oil gets dry, then the surface becomes matt black. Wipe them out to make it gloss again
Our last manufacturing process for the black chrome plating parts is to apply oil for maintaining the gloss part harder. To keep their best quality, we suggest following these steps within 4 weeks upon you received them.
2. Aged Plastic Discoloration Issue
In case of platic parts in white, aged white and ivory colors, they may discolor over time as below.
If ordered separately, we cannot guarantee the same color as the previous one.
So we'd much appreciate if you could order these plastic parts as a set unit so that we can match the color.
