I used the marine spar varnish and mine looked good after 8 years with 4 good coats on all sides. On the Mar-K Bed forum he suggest using a primer before the spar urethane. I think the post was around Jan 20th as I ask the same question as you when I wanted to freshen up mine. On that post Mar-K list the experiments that have been done, how long they have been in process and so forth. It is a good read. Just more info!!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
