So I had my dealer do all my upgrades when I bought the truck last July, including powder coating the stockers. Well, they replaced the nice GMC stamped center caps with plain standard ones which they sprayed black and put red GMC vinyl stickers on them. At first, I just went along with it. After the paint rubbing off them twice because they weren't sanded well and no promoter was used, I told em to just give me my stock caps back and I'll figure something out. I had a local sign shop cut out some logos to scale so I could stick the stamped logo on the cap before I spray them. I sanded the crap out of em, laid the logos, tak-ragged, sprayed with adhesion promoter, then sprayed with duplicolor satin black spray paint. I pulled the vinyl pretty quickly after spraying. Think I'm happy with the results. A little of the chrome trim was left around the letters too, much cleaner and nicer than the quick cheap get it done ones the dealer did....
