Haven't work construction for over 20 years so no longer have tung oil.
Bench (a slider actually) is made in China and has a faux bronze powder coat on the metal, I live a block from the ocean so the metal frame will probably rot away before the teak.
Therefore I'm trying to do this on the cheap... as I said I already have the linseed oil and that costs me nothing.
I'll check west marine and see what they have.
Thanks for the replies.
