Help PC over chrome

[luv2fly]

Hello all. Fairly new here. Been powder coating about a year. Up until recently I've been doing this for myself as a hobby. Posted a few pics in a forum I'm active on and now I have business! Thtas teh good part, now the bad.

Everything I've done so far has been painted, nothing chromed. I've recently tried doing previously chromed parts and I keep getting blemishes. Although the parts are cast, it doesn't look like outgassing to me. Looks like lint or contaminent under the powder. I blasted all the chrome off. Copper and nickel still remained. prebaked, acetone, propane torch, reflective chrome powder, and they look like ****. Will get a pic up when I can. Any ideas?

What exactly does **** look like?

I really was just looking for a description, but pics are even better.

Hello pcbeachrat
I know this is a old post but I have a question for you. Are you using regular easy off oven cleaner (in the spray can)? How long do you let it set with the oven cleaner on it? What is your baking soda solution (what are you mixing together)?
