Maintenance and Refit
How is yellowed or dull gelcoat restored?
Dullness is the UV-oxidised top layer of the gelcoat and can be polished off, but every pass removes material. Yellowing usually runs deeper, and repeated polishing consumes the gelcoat.
Why it works this way
Once the remaining thickness reaches a critical level the answer is paint rather than polish. That distinction is established by measurement during a survey.
