I've dipped a ton of different badges and emblems and 5 different sets of wheels. Prep work is obviously key. Start with as clean of a wheel/emblem as you can get, then a light fog coat, then 4-5 heavy coats. I don't remember the flash time between coats, I just followed the directions on the can. I have yet to have a wheel or emblem/badge peel off. A lot of the areas I hunt in are covered in short, 8-16" sage brushes which are constantly scrubbing against the dipped wheels and never an issues. I've also never had an issues with a power washer. On my first Xterra, I dipped the wheels and later decided to remove it and thought the pressure washer would make quick work of it, but I was wrong. I held the tip 1/2" away and it didn't damage anything. Granted, it was a public carwash handheld sprayer, but it still had some kick to it. I ended up having to gouge it with a hard plastic scraper, then hand peel it. Once I got to start peeling, it came off fairly easily.
Going with plenty of thick coats after the initial fog coat held up for over a year and also came off fairly easily. When you go with only 1 or 2 coats, it tends to not hold up and removal is difficult. The wheels on my current Xterra were dipped a year or so before I got it (according to the PO) and I can tell they only went with 1 or 2 coats. That stuff is baked on and damn near as hard to remove as powder coating, so it's staying, lol.
