I bought a set of five 16×7 Unique Series 42 wheels (with gently used stock tires) from
doubleajaybrock last weekend. He included the chrome center hubs, but I didn't really like the way they looked on the wheels, so they are
for sale on eBay.
Not using them left a 3¼" hole in the center of each wheel. That looked like crap with rust showing through, so I decided to paint the wheel mounting surface black to match the wheels. A trip to PepBoys and $15 later I had two options to cover the rust: Blue Magic Rubber Underoat and DupliColor Truck Bed Coating.
After some sample sprays on a piece of plywood, I decided to use the DupliColor.
I jacked up the passenger side and took off the aluminum wheels. I definitely had some rust awaiting me, but nothing really bad. I used 150 grit sandpaper on the rust and kept blowing the dust off.
When the first wheel had the loose rust sanded off, I used blue masking tape and a trash bag to cover the wheel studs and circumference of the "hat" to protect the disc brakes from overspray.
From there it was easy to apply the "paint", recoat it 10 minutes later (per the directions on the can), and peel off the masking. (I used the same masking for the whole Jeep.)
Here is a picture with the masking removed.
I did the same on the other three wheels.
The only real "challenge" I faced was that I initially masked off the large nut and bolt on the front wheel (that attaches to the CV joint). That looked really bad, so I re-masked the studs and brakes and painted the nut and bolt. See the bottom right of the picture below.
It was a little hard to fill in the threads of the bolt without spraying so much that it would drip, but I was just careful and used a bunch of really quick sprays.
While I was at it, I exposed the pinch welds and pounded them down (in anticipation of an upcoming lift).
I would have been remiss I didn't cover that in the DupliColor as well.
The next day, we took the pooch to the dog park.
Since I did this on a Saturday, I let the DupliColor cure for half a football game before I put the wheels on and switched sides. In all, it probably took me 4 hours or so (with curing time).
Jack stands and/or a floor jack would have made this go much more quickly (and probably a lot safer too). If I had been able to do all four wheels at the same time, it would have been ~15-20 minutes per wheel (sanding, masking, and painting). It's probably a 60-75 minute job for most, plus curing time.
