There comes a point in time when the gelcoat has become so deteriorated that it cannot be restored.
Oh sure it can be compounded & resealed with any number of DIY products but they will not last very long.
The only restoration method, not cheap, that will last is a thorough preparation and recoating using a product such as Awlgrip or Emron
These are extremely tough marine epoxy products that, finished with a couple coats of clear coat, will last for many years without the labour needed to keep gelcoat looking good.
I stress again, this type of coating is not cheap, but the results achieved by a professional, WOW.
