This has probably been beat to death already, but I didn't see any references to it. I have to redo my teak rail trim and swim platform. Again..Could I use another product that would last a bit longer than teak oil? I generally power wash the wood, let it dry and apply a couple coats of teak oil. It looks good only for a short time. Can I use a wood sealer like Thompsons deck sealant or something? Any suggestions? Thanks! Den
