Cetol doesn't last a lot longer than varnish. It might last
about 10% longer, tops.


b.... As far as "meticulous maintenance of Cetol? About once a year
you wipe it down with a kitchen scrub pad and water. Then recoat. No sanding
required.

If you keep your boat further south, the UV will rip both
Cetol & varnish off in a matter of weeks. In fact Cetol may
suffer more because of the darker & less reflective surface.




Oh yeah... If your varnish does not contain pigment, it does nothing to protect
itself OR THE WOOD from UV degradation.

Does wood "degrade" from UV? Maybe that's why trees don't
grow in tropical latitudes?

Anyway, there are lots of varanishes with high UV protection
that are relatively clear. None look like barn paint AFAIK.

.... That's why varnish needs to be stripped
so often.

If it's properly taken care of, varnish doesn't need to be
stripped.
