I've used plastidip on a couple of things. It isn't durable enough to withstand repeated abrasion as a switch would receive. It's designed to be removable, so there isn't a positive bond.
I have resprayed my window switches with a Krylon spray made for plastic. They have endured well for a number of years.
You have to really clean everything well. I snapped off the switch covers, wet them, then used a toothbrush with Dawn to scrub them, trying to get any oils and buildup off them. Then I used a Chore Boy to remove the chalking or you can use the Scotchbrite pads for cleaning glass cooktops. Once they were dry, I sprayed them, but I went back with a gray color that was slightly darker than the original. .

Yeah, the mask on top is mine. The one with the ear loops tied is my 9 year old granddaughter when we go shopping or to have a sit-down bite to eat when I pick her up from school. I keep a similar combo in each of the 3 vehicles, plus a couple of unused spares for any unexpected passenger.
