The largest source of wax and other items would be from automatic/touchless car washes where the high pressure jets spray soap, water, and wax onto the panels. I did receive word back from CarWorx as well. They said that see the issues with flaking, fading, and splotching (if that is a word) comes with overapplication of the RR product, especially with multiple coats of RR applied too heavily.
They recommend two very light coats of RR with plenty of time in between coats to allow for each coat to fully penetrate and dry. I have follow up question with them on how to remedy this problem once the RR has been over-applied. I will update the group as I get their responses.
