For anyone who wants stock-looking center caps for their ESM wheels, or any other aftermarket wheel, here's how I made mine. They turned out pretty good.
1) Prepared the center caps. I cleaned the center caps with alcohol and applied 3 or 4 coats of black Plasti Dip. I did this so there wouldn't be any possibility of damaging the finish if I ever wanted to remove the decals, and the Plasti Dip peels off easily when you need to. I peeled the Plasti Dip off of the outer rim of the caps and just left the center part (where the decal will go) painted.
2) Made the image for the center cap. I downloaded a chrome-ish Acura logo and added a round black background layer. You can use any color combination you want, of course.
3) Made the layout. Using MS Word and a standard template to match the sticker paper I was going to use, laid out the center cap images so they'd be in the center of each sticker. The paper I ended up using has four stickers per sheet, but you can also buy paper where the whole sheet is one sticker.
4) Printed the labels. I bought water resistant labels for laser printers at Office Depot. You can order higher-quality paper online, but this stuff seems to work fine. Office Depot printed the labels for me for about 50 cents a sheet.
5) Apply the labels. Just cut out the stickers and stick them on the center caps. It's not difficult, but you need to stay with them for a half hour or so in case any air bubbles pop up. Mine had a couple of bubbles, but squashed them when the popped up, and none have reappeared. I previously tried two different sets of vinyl center cap labels that I bought online, and both developed air bubbles. I think it's because our center caps are so convex. After this step there were a few pin head-sized white spots where I had rubbed the black ink off with my fingernails when smoothing out air bubbles. After touching them up with an india ink pen, the white spots are gone.
6) Apply gloss coat. At this point, the center caps look pretty good, but you can tell that they're paper. I sprayed on a few coats of Krylon Crystal Clear acrylic coating to waterproof them, protect them from fading or yellowing, and make them shine. This hard, glossy coating makes them look and feel like plastic. You wouldn't know from looking at them that they're home made.
That's it. I don't know for sure how long they'll last, but after a month of use, two washings, and a professional detailing, mine look as good as when I made them. If you're interested in making some, shoot me a message and I'll send you image I made. A few pics of my caps are below.
