Why Has My Coating Stopped Beading?
Reduced beading does not automatically mean the coating has failed. Surface contamination, wash-product residue and wear can all change water behavior. The sensible next step is to review the maintenance history and inspect the surface, not immediately assume the entire vehicle needs polishing and recoating.

Look for a pattern
Compare panels that receive different exposure. Lower doors collect road film; horizontal panels may see more standing water and fallout. Note whether the change is localized or widespread. Photographs taken during a normal wash can help explain the pattern, but they are not a reliable remaining-life test.
Review recent product changes
A shampoo, spray protectant or drying aid can alter how water behaves on top of the existing coating. Tell the shop what you have used and when. More water beading after a spray does not prove the original coating was restored, just as less beading does not establish that it is gone.
Agree on an assessment before renewal
Ask whether a compatible cleaning or decontamination step should be evaluated first. If wear is confirmed, discuss the affected coverage and preparation needed for renewal. Keep the decision tied to the vehicle’s condition, the installed product and your goals instead of an arbitrary birthday for the coating.
