semco vs cetol

[foxglove]

Has anyone used both products, Semco and Cetol, and drawn a conclusion for use on exterior teak?

I've never used either but I need a finish that will stand up as long as possible because over the years, I have sanded too much wood off the boat. I can't sand too much more so longevity is my most important goal.

Thanks to any and all.

If you really must, pick Cetol. I've used both and am currently removing Semco applied by the PO. The Cetol will last longer. Both hide the teak too much for me. I'm now using Epifanes Woodfinish, more or less a varnish that holds up well, but enhances the wood IMHO rather than hide it..

Here's 2 coats of Cetol and 2 coats of Cetol gloss. Lasts long...touch up with gloss with no sanding when needed. I think the Semco is too dark.

hey, do you have to go to bare wood to lay on the Cetol, vs. sand prior varnish smooth?

If "Yes," are there any finishes that can go on (without going down to bare wood) ...I get confused between poly varnish vs. traditional, whatever that means these days.

I mean, obviously, same varnish on top of old varnish. But this is a PO unknown.

I used cetol last year and my results were more than impressive. One year later and my teak still looks good and no touch ups required. I put about 6 coats on and sanded lightly with a bronze pad between coats.

geary...if the varnish is worn and flaking then you need to go to bare wood regardless of what you use.

A photo from early last season with four coats of Cetol Light over bare teak - applied the year before. In a couple weeks, I will apply two coats of Cetol clear gloss - which should look similar to Cams' teak when done.

Thanks for the input. Your boats look great. SailorMitch, you've helped me again.

I ask because a recent article in Cruising World about bestupgrades included removing Cetol and applying Semco.

I'll keep watching for more replies.

Good luck Geary

Let's say varnish is tired, but not flaking. Can't I sand with #220 and keep going? Q: can I switch to Cetol, mid-way, or am I asking for trouble?

Also, anybody use Marine Natual Teak yet (the new version of Cetol)?
