Watco Exterior Oil Finish

[OutlawDrifter]

I think it depends on your desired results. I recently researched this topic and found that Tung Oil is the best product for a bed that gets used. That's what I applied to the bed in my '49 GMC. Four hand rubbed coats and it beads water nicely.

The only down side to the Tung Oil is it does not have UV blockers, so the wood will age, which in my case is the desired outcome. (Even though my pickup sits inside 95% time, only sees sun when it's driven.)
