I need some help on how to restore my RX7 wheels. 2 of them are corroded a bit and I want to sand them down so I can paint them. The other 2 are in a much betetr shape, just a bit dirty.. So those will only need prepping for the paint.
Can anyone tell me how to start with it? Sandblasting them is a bit too expensive and would ruin the low budget idea of these wheels.
What grit sandpaper should I go for, or is there maybe another option to try like a wirewheel on my dremel or something like that?
Here's a picture of what I'm working with:
The two on the right are the good set, the two on the left are the 'bad' set.
All tips are welcome
