A body louvers

Rob, it's not necessary to have the louvers in hand for a price quote; all your photos are very helpful.

Powder coating lasts longer and adheres best when shot over bare media-blasted metal stock so clean production pieces would be best for me.

If you go with painting, something to consider is that your guy will be painting right over any chipping, gouges or mars in the base coat that occur during normal production. There's no tactful way to say it other than it will be pretty obvious up close that your finish may be less than perfect -- I have no doubts that some of your customers will prefer an out-of-the-box-installation rather than first going through the hassle of cleaning up the paint job to save those points at future car shows.

Another option is to offer a good / better / best end product. Some customers might want bare metal so they can customize it and do as much of it themselves as they can (good), others can do mechanical work but avoid painting and finishing like the plague (better), and the rest would love it to install itself once they take it out of the box (best).

If you decide to get these setups powder coated and want to save your customers as much shipping cost as possible, I'd be willing to coat them per the customer's specs and ship them direct. Of course, the first few would go to you to make sure you're happy with the quality ... but I also know that if YOU don't look good showing off my work, I don't look good either so you wouldn't have to worry about shoddy workwomanship lol!!! (One thing I tell customers is that if I wouldn't put my work on my own car, I'd never ask them to put it on theirs. The same applies to your louvers.)

Rob, please feel free to give me a call at your convenience (or PM me with your number and I'll call you) so we can work out the details whenever you're ready.
