First, let me correct myself on one point, outgassing is NOT caused by under or over curing a part. It IS caused by air entrapment in the casting. Preheating the part can help keep this from occuring however there are powders that are designed to allow the part to outgas. These are typically higher quality powders.
Second, what I was referring to with regards the subject of grounding, you are probably aware that powder is designed to be applied electrostatically requiring the part you are painting to be grounded. If you don't have a good ground, the powder won't stay on the part. You can cheat this by heating the part before you paint it. This causes the paint to pre-gel and stick to the part.
Go to www.powder-coaters.com to see more.
Finally, I am NOT a coater, but a supplier.

I had taken my cover (over the distributor) to the powdercoater a couple weeks ago. This way if I didn't like it - not expensive to get back to original.
After getting home and striping it - putting it on the engine ....... I'm excited now about getting the valve covers, tubes and plenum done.
Was really pleased the way it turned out!
Thanks for all the information ....... it really helped talking to the pc'er and understanding the process and the steps in getting to the final results.
Now we'll see how good I do smoothing out the magnesium valve covers.
