Masking Before Polishing and Coating
Protect sensitive trim and edges during preparation, and remove masking at the right stage so residue and moisture do not interfere with coating.

Identify what needs protection
Textured plastics, rubber, badges and fragile paint edges may need protection during polishing. Map these areas before starting. The aim is to prevent abrasive or cleaning residue from reaching materials that are difficult to restore, while keeping the actual treatment boundaries clear.
Select masking material appropriate for the finish and planned conditions. Adhesion should be sufficient for the job without risking damage on removal. Test uncertain or repaired surfaces.
Keep masking useful
Apply to suitable clean, dry areas and avoid hiding damage that still needs inspection. Replace tape that loosens or collects heavy contamination. Do not assume covered edges can be ignored during final cleaning.
Before coating, remove masking where necessary for the approved application process. Check for adhesive, polishing dust and water along the former tape line. Use only a compatible removal method for any residue.
Inspect the boundary
Paint next to plastics or film requires careful levelling so product does not accumulate in a joint or contact an unsuitable surface. Do not coat a concealed edge blindly. At the end, verify that all masking has been accounted for and that the transition looks clean. A tidy boundary contributes to finish quality and avoids creating a later maintenance problem.
