I have used this Schreuder Exterior SparVarnish
on a wooden (ash) pickup truck bed.
The bed is a few years old,
but it is stored inside so this really doesn't count.
This 'pickup' truck belongs to my father
(along with all the firewood behind it).
He and I are both 'woodworkers' I guess, we're just different.
We had fun doing this truck bed.
