Always prepare!!! There are always some oily residue on the surface like oil, car polish etc. so a good rubdown with 120grit water paper, and rinse with clean water and you should be ok. Remember to remove the balancing weights otherwise you will have ugly looking patches on the rim where they removed the old once when rebalancing. (and then take the wheels to be balanced again)
With Hammerite you get in a smooth and a hammered look, also mat or gloss, so the options are numerous!
Yes I agree, you have to prepare the rim for the new paint to stick otherwise it will just peal off in a couple of months.
I prefer 400 grid sand paper as 120 can leave scratches which you will see after the new paint has been applied. Allot of people think that paint will cover scratches...... it doesnt and you will se them.
Luckely with rims it does not have to be ferfect so no one will notice and if you use plasticdip or something similar it might cover marks and scratches.
Another question for the Plastidip. If you have to move the wheel weights for balancing purposes, will it damage the plastic covering? Can you then repair the mark by touching up the paint.
How about just re-spraying the rims with normal paint(2K)?

But do you need to sand the rims, when you going to respray them with plastidip or flexidip?
Just remember this is not permanent. 2-3 years. It becomes harder to remove the longer it is on. 2K will be a permanent option. Will go 2K maybe next time. I know there is also a can spray paint in America that can be a permanent option for the oukes without spray equipment like me. Can not remember the name, but it is also not available in SA.
I have done my wheels with 2k and still looks brsnd new after almost a year. been through mud several times and high pressure hose them with no problem.
Here are some before and afters, cost me less than R150 for all 5 wheels...... and some sanding
