  • Rub a little lightweight motor oil on the decals and it will give the same LOOK.
  • Good stuff. Been using it for years, both in marine and RV applications.

    It will temporarily make gelcoat look nicer but it will not last like a good quality marine sealant like Meguires Flagship.

    303 breathes new life in my 16 year old decals but they are what they are, poor quality to start with, nothing like marine quality decals.

    Same question came up years ago. I tried some 303 on a small portion of my fiberglass siding. I don't think you would be happy with the results; streaks, not good.

    Many of us use Wash Wax All for the main fiberglass parts of the RV. It was developed for the aviation and aerospace industries intially.
