Let me clarify something. When most guys ask about rattle cans, they are referring to Krylon or similar that the local box store has on the shelf. Stay as far away form those as you can, they will not last at all. But there is a company that makes spray cans with dual chambers for mixing 2K products, epoxy primers included. The down side to these products is that once it has been "mixed", the contents have begun to harden, whether you spray for one minute or empty the can. There is a 24 hour life at this point, so no putting it on the shelf and coming back to it next week, next month. For your steering wheel, this may be the ticket. For small parts that don't use up but about 1/3 of the can, the hardening process will cause considerable waste such that now mixing your own and using a spray gun starts to be more cost effective. While these guys state they have the best UV protection of any spray can clear, most have none at all, so take that for what it's worth. I doubt they are better than something mixed and sprayed proper. So, it is what it is, and is likely the best you'll do out of a spray can. Here's a link:

That means gloves, eye protection, ventilation, and respirators are prudent. Proper spraying with a paint gun using iso's requires an air-supplied respirator, that should warn you how serious to treat this stuff. It's not your typical Krylon.
For all the guys who frequent Eastwood, I've always said they were a glorified re-seller and anything they sell can be found cheaper, elsewhere. Case in point, their price is over $7.50 more per can.
