Using the TruDesign Install Tool allows one person to fit Skin Fittings (thru Hulls) without the need for a """"helper"""" inside the boat at the same time.
Marine adhesive sealants such as 3M Fast Cure 5200, Sika 291i or Sika 591 can be used. West type epoxy system can also be used, this method makes the Skin Fitting an integral part of the hull.
