prep work to get it to hold for a month = 0, just clean them well and done.
If you were to do it permanently then yes you would need to clean, sand, sand more, prime, sand, prime, sand, sand more, paint, wait, paint, wait, paint, wait, sand, clear, wait, clear, wait 24hrs, sand, clear, sand and then polish etc.
The ease of "eh im over it" and peeling it off is a real bonus here. Your wheels go back to normal colour, no tideous prep work etc... and its reasonably cheap. Depending on what paint and how you use it 2 cans should be plenty. Hell ive done a whole engine bay with one can before, 3 layers + clear, you just gotta be careful with how youre using it to get the most out and cover a big enough area.
I reckon this has merit for temporary bossin. Im keen to paint the moto wheels red with this stuff.
