I kind of agree with not putting the coating on the wheels if your wheels are buffed and not machined. Let me just knock off some advantages and disadvantages of coatings from the top of my head.
1. Yes, uncoated wheels do require more attention.
2. Coatings protect wheels from minor scratches, but not major ones.
3. Coatings are not 100% optically clear, so a coated wheel is not as shiney as a non-coated wheel.
4. Regardless of the coating quality, coatings eventually cloud and peal over time. That is because they react with sunlight, cleaners, and road chemicals. The more you care for them, the slower the deterioration process, but it is unavoidable.
5. Once coated wheels are damaged or degrade, to my knowledge, they are unrestorable (to 100% condition) except by stripping, repairing, and reapplying. The damage or degradation is pretty well locked in until you do that. Uncoated wheels, on the other hand, can be restored to show condition in just a few minutes through buffing.
I have a set of beautifully buffed rims with no coatings and I like them, but I think the issue of coatings verses non-coating is more a matter of which useful option suits your needs/desires best rather than one being better than the other.
