I’ve made several lg planters for patio boarder and would like to maintain the “new ” cedar look for as long as is poss. HO suggested tung oil because he uses it on boats . I’ve done floors with it but it cautions not for exterior use. Area is in NE so weather is a factor. The wood was kd and not seen any moisture in about a year so I’m hoping to get good penetration.
Any direction is much appreciated.
Cheers c
