  1. would owayell be any good on caravan gelcoats ,the front of caravan is white and oxidizes with the weather and traffic films ,regards john

    1. Hi there John,

      Yes, Owayell should work well for this purpose. We do however recommend purchasing a sample pot first (£5 with free delivery) and complete a small test first to be sure.

      All the best,
      The Owatrol Team
