I have a set of these standard Rover Minilites and I want to refurb them to look like the ones in the pic below.

to...

Here is the plan:
1) Have the wheels blasted to strip back to bare alloy.
2) Rub down any imperfections (slight curbing to a few of the rims).
3) Start polishing the rim. To do this I will do as follows:
- Mount wheel on front hub of a mini with the front of the car in the air
- Start with some corse wet & dry paper
- Put the car in gear with the engine on to get the wheel turning
- Hold the paper to the rim to start the polishing, working to finer and finer grades of paper
- I should then end up with a highly polished rim with the minimum of elbow grease
4) Clean wheel thoroughly
5) Get some pin stripe type masking tape and mask off polished rim that I want to keep.
6) Etch prime wheel
7) Paint
8) Lacquer
9) Remove masking tape
10) Finished product
So that's the plan....here are my concerns about my plan:
- Could possibly be dangerous having my hands so close to the wheel while it's turning (I think I'll be fine as long as I'm careful and wearing some gloves)
- Masking off the area I want to keep could be an absolute nightmare. I don't want to end up with a wonky line. My idea to solve this problem would be to find a dispenser for pin stripe masking tape like one of those tip-ex mice (does anyone know if they exist/where I could get one from?). I would have the wheel mounted on the hub and my elbow resting on something steady like a step. I could then turn the wheel with one hand and hold the tip-ex mouse thing to the rim with my other hand, eventually creating a nice steady line. One of the biggest problems with masking this bit is that those rover alloys don't have a sharp lip to them, they're rounded.
- After it is all painted and I remove the masking tape, I could be left with a ridge. I'm guessing that this ridge would be delicate and susceptible to chipping/peeling off of the paint, possibly even when removing the tape. Should I remove the tape before the paint is fully dry to solve this problem? Or should I lacquer the whole wheel including the polished rim to effectively "seal" the whole thing. I'd be worried about loosing the polished finish if I were to do that.
