I suggest Plastidip...can't go wrong. If you don't like it, peel it off. It also doesn't require much prep other than a good wash. Completely reversible, unlike the Krylon...
It depends on what you're looking for. CLEARLY Plastidip is the choice for temporary applications. But if you're looking for a good, permanent, durable paint finish, then Plastidip is NOT the recommended solution.
I plasti dipped my rims, lasted till I had tires replaced. Well over a yr, then I re did them. As long as you clean the area you want, it will stay on till you choose to remove it
