As there have been some questions as to wether or not the AG CWC was safe on all wheel types, the truck I was working on today offered up a great opportunity. These wheels are uncoated Alcoa aluminum wheels that were recently polished. There is no clearcoat or any type of sealer on these wheels.
Here are the wheels as they arrived
AG CWC soaking. No foaming sprayer was used. Just an off the shelf trigger sprayer.
After cleaning
I allowed the wheels to dry completely as we all know wet wheels can look clean, but may not be.
After one coat of Blackfire All Metal Sealant.
