Default Powder Coating Question

To apply a Chrome finish to my valve covers, what is the proper technique. I have stripped the paint off of my 82 valve cover, and scrub them in acid to remove any contaminents. I was going to bead blast them today, but I had to much air moisture in my lines due to the humid days in Ga. I will probably pick up some sand to blast them, or use my glass beads in my blaster while spraying in my cabinet.

I saw how nice Wayne's covers turned out, and decided I want more than the stock look. I just don't want to have to do them twice.

Steps
1. Clean
2. Blast
3. Outgas
4. Clean with Acetone until good.
5. Spray with Chrome PC
6. Spray with black between fins.
7. Clear

Please correct me where needed. I have only done some Gloss Black PC.

Look like good steps to me. I would add a cleaning step after blasting,i like to wipe them down with Acetone real good before outgasing,and then wipe with Acetone again before applying pc.

Do I need to do anything between the 2 colors steps. Spray the chrome, cool down, tape, then spray black, then bake again, then clear?

No more cleaning is needed, i like to wear rubber gloves while handling the parts to keep from leaving oily finger prints.

The good part is,if does not turn out quite right you can always blast it clean and try again.

If you cannot blast it off,Eastwood's has a chemical stripper just for removing pc.

You guys. I blast them, coat them, then bake them. Never had a problem yet.

You can do that. But if you want the finish to be as smooth as a baby's butt with none of those little pores and orange peel,then you need to put in some prep work.
I have skipped a step or 2 before but i had a lot of tiny bubbles from the out gassing
