Powder coat dilemma

I have done a little research and I don't think there is a solution but thought I would put this out there. Very unique problem.

History:
I recently purchased a project truck from an estate. About 90% into a full off frame restoration. With the exception of the cab all other sheet metal appears to be new. Fenders, bed, hood and running boards. Truck has already been painted, or so I thought but I do not like the previous owners color choice. I was planning on new paint.

Issue:
The PO owned a commercial factory that did powder coating for John Deere. He took advantage of this and after doing a thorough inspection of the truck I have concluded all the sheet metal is powder coated. This would be a great thing if I liked the color choice. I have already spoke with one local paint shop and they will not attempt to paint over powder coat. I also spoke with a local powder coat business and they can not powder coat over powder coat. They would have to strip down to bare metal (significantly adding to cost) and even told me media blasting would not remove the existing powder coating. It would only etch it some.

Thoughts/solutions.
At this point I might have to learn to like the current color.
Any thoughts from the group.

FYI - 1947 Truck is Silver with maroon fenders and running boards. I don't mind the maroon but do not like the silver. The silver really hides the beautiful front badge on the truck. They sort of blend together.

From a quick search, it is possible to paint over powder coating. The main issue is to roughen the surface enough to get your paint to stay on, as powder coating is typically very smooth. I think a brush-off blast would do the trick, or complete sanding, where getting to nooks and crannies would be difficult. That's probably why your paint shop didn't want to take on such a job. Any way you approach it, it ain't gonna be cheap.

Found this on the web. Paint over powder coating. [pittsburghsprayequip.com]

This has been talked about here on stovebolt as well. Link

Sand the thing with 180 grit, then spray a DTA (direct to anything) epoxy primer? Prime it, block it, seal it, then color/clear? Or single stage if that's your thing. At least, that's what I would do.

Silver and maroon sounds like a good combination. How about just changing the color of the front badge?

One thing to remember when deciding what to do. Paint checking is caused by paint not expanding and contracting as much as, or more than, the surface it's attached to. The thicker the coating, the more likely this will happen. Powder coating is very thick compared to paint. If you decide to paint over the powder coat I'd advise you to remove as much as the powder coat as you can. If you leave it full thickness you'll have a very thick coating and 'could' have checking issues after a period of time.

I asked a bodyshop friend of mine who has seen everything in the last 30 years.

He said scuff it, shoot it with primer. Block it if you want, but if it was powdercoated and looks good probably does not need it, and then shoot your flavor of color.

He is assuming it will not be a high end show truck. If it is, then you will have to remove first.

I appreciate everyone's input. Paint or not paint is a simple question that can be debated all day long. The checking possibility Tiny brings up is the kind of issue/consequence of painting that can really drive a decision. No one wants to go the the effort and expense of something like paint to only have it fail in the near future. I think what really complicates this discussion is the large areas involved. A lot of powder coated parts associated with cars/trucks are typically smaller pieces. Usually wheels or a manifold. I would have to think a large area like a fender or hood increases the risk. Maybe not?

I would bet that there are numerous folks across this country and abroad who would love that truck with that color combination.
If you leave it as is, but find that it won't grow on you, you could sell it for a profit (assuming that you stole it at the auction) and look for another one which you can paint whatever color you desire.
