A lot of people talk so much crap about plasti dip, I did my challenger wheels, held up great... Did my mustang with in the first week of having the car, still holding up great. I go to the local car wash and use the power sprayer on them, never had an issue. I know my car only has 1700 miles, but she gets washed every week or so. A the very least rinsed off.. Powder coating is great, but expensive. At the very least the plasti dip will give you an idea of what your car will look like if you do choose to buy new rims. What you could do is use you stock rims in the winter, put some good snow tires on them, and then buy what wheels you want for the summer fun driving.
