Cetol Vs Honey Teak
The problem with any coating is that it needs one or two coats when it still looks good to prevent a lot of extra work. This is a strange disipline. This generally involves lightly sanding off the outer layers and then adding 2 or 3 coats. One is never enough because of damage that need repair. You can spot fix the repair areas and then overcoat the entire area, but 2 coats are minimum to cover the sanding marks.
When my Cetol failed it was dramatic and required complete removal. Weather prevented me from doing it just in time to prevent failure. It flaked off and the wood turned black under it. Not just in spots, but everywhere.
