Mistake?? Painted chrome
I've done this a number of times using the method I describe with no problems. Unless you are going into the higher level of powder coating, in my opinion, there is no advantage to conventionally painting your parts. It's simply another way to lay on paint. It has advantages in the industrial process, as the turnaround time is much less, but people have confused that process over the years with ceramic coating, porcelaining, and anodizing, all of which are more durable. There are levels of powder coating which ARE more durable, but that's not what's generally available to the typical user, unless you do your research and are willing to pay the freight!
The reservation I have with mineral spirits is that I've never used it, and I don't know if it leaves an oily layer on the surface...if it doesn't, not a problem. I assume you're using rattle cans, if that's all ya got, great, the layers aren't very thick...on the other hand, don't lay on TOO much paint, either!!!
The advantage of powder coating for a guy in your situation is that you can yank everything off, take it to the powder coater, pick it up a week later, one and done. If you do the job correctly yourself, there will be nothing wrong with the results, and it looks to me like you got a handle on it!
