I’ve built a custom travel trailer that has wood siding. I’m using Wooscapes exterior water based stain from Sherwin Williams. This has a sealer in it that all told is really quite effective. But being on a trailer that is on the road often, the siding takes a beating. This has meant refinishing the wood annually – a bit of a chore to deal with every year
I am pondering how to get more life out of it by perhaps adding some sort of a finish coat. But I’m reading on the interwebs that poly coats over this type of sealing stain is a bad idea. I’ve gotten some recs from a couple people that a spar urethane like Helmsmens might work, but that there’s some risk of yellowing and the stain failing underneath the urethane.
Any thoughts on what might work in this situation?
