Unwrap your boat and get it professionally detailed. Your detail service should include an acid wash as needed, compounding as needed, buff & wax, interior deep clean of vinyl, canvas, carpet, compartments, live wells, and vinyl protectant.
Have your boat professionally washed weekly (depending on use) and be sure to wash it down after every use. Hard water, invasive species, and acid rain will etch water marks into your gel coat, metal or glass if not removed.
Winterize your boat; draining the lower unit, treat gasoline, spark plugs and professionally shrink wrapping it order to protect it from our harsh winters. Make sure that your boat is clean and ready for next year.
