okay, I get it. If you want it fast and flawless, just buy new rims. You'll get the exact look you want instantly, often with better quality than a quick paint job. You can always sell your old ones to offset the cost!
If you're impatient and you don't want to deal with the drying time and all the prep work, just buy a new set of wheels. You can get a brand new set of silver rims and have them mounted and balanced in a few hours. That way you aren't waiting for anything to dry and you can get the exact look you want without the hassle. You can definitely find some great looking aftermarket wheels that will fit your Malibu perfectly. You don't have to stick with OEM unless that's a must for you. Check your options with big online retailers like Discount Tire, Tire Rack, or Fitment Industries. They have vehicle visualizers so you can see what the wheels will look like on your specific car, which is super helpful when you're trying to make a decision.
