I am in the process of reviewing some of the Marine varnishes to apply over my epoxy/fiberglass skin. There is a lack of head to head comparison amongst the various types of tung oil/urethane finishes, and the various UV resistance components.
Is there any feedback from members on success or failure with products such as Epifane, Interlux, LeTonkinois, Zspar or Petit? For example any spalling or flaking after a short time, amount of sun the trailer sees, how many coats were appliess?
Thanks
