Without more information about how you've gone about polishing the trim, I would say YES. The aluminum "chrome" trim pieces are covered in an anodized coating, which must be removed before polishing. After polishing you will need to either re-coat the trim or re-polish it frequently (depending on the exposure to the elements).
Remove the trim from the truck. It's been reported that you can use EZ OFF oven cleaner to remove the anodizing but I have not tried it, I use an anodizing remover. It needs to be soaked in the solution and then washed off. You can make a tube out of PVC pipe and fittings to soak the longer pieces in. Much is made about the need to keep polishing the parts but it really isn't that bad if the truck stays indoors most of the time. Clear coating the parts is a tricky process to get it to look right...spray cans aren't going to do it. You could get the parts re-anodized but that is costly. A set of reproductions solves the problem quickly but will run over $500.
Should you be able to find out what kind of money was required up front before the first piece was stamped, or how much trouble they had finding the right alloy to make the thin molding that didn't change color or crack, it could help you understand the cost.
To help you thought process get started it was well past $100,000.00. Rick and his wife eat good, but they are not rich by any means.
