Loose or unsuitable attachments need assessment as attachments. Coating over them does not establish that they are correctly installed or compatible. The metal panels, fasteners, and surrounding details should be reviewed before surface treatment.
What to do next
Ask what mechanical repairs are included before coating. Have the contractor explain how replacement components match the existing system. Compare the finished coating scope with the underlying repair list so visible coverage is not mistaken for correction of every defect.
