What do I use on my teak?

If the soft part of the grain is gone, you may have to sand it a lot to get it smooth, so sanding with 60 grit is ok. Bare teak will quickly clog fine sand paper; I’d give it a final sanding with 180 grit before 1st coat of varnish. Follow their directions . . . thin first coat 25%, then thin the next 4-5 coats about 5%, allowing it to dry for 24 hrs between coats. No thinning required between subsequent coats. If you use Epifanes Wood Finish Gloss you won't have to sand between coats if recoated within 72 hrs, although if you get bubbles or bugs in it, I’d sand it locally with 280 grit. Before the last coat I’d sand everything with 320 grit or you can use a red 3M pad to knock off the gloss. I did mostly wet sanding of the varnish to avoid clogging the paper.
