I have brand new Jenn. 49i with teakcockpit seats and sole, dont realy like when it turns gray but also dont want to constantley work on it, has anyone tried Ultimate Sole in the cockpit, I do have Bimini and Doger but that will not keep cockpit totally dry.
I have enough wood on my boat that needs care so I just let the cockpit go gray and clean it from time to time. I've used Ultimate Sole below and rather like the results but I believe they will tell you it is for interior use only, no UV resistance. I would NEVER use oil on exterior teak, way too much upkeep. I've no experience with TeakGuard so......
I would ask the folks in your area who have good looking teak. In our climate, you would have to re-oil the teak every month for oil to work. I use Cetol with Cetol clearcoat and have to give it one maintenance coat a year. Maybe in Canada, the UV ray situation is different and something else works better. Some people don't like the looks of Cetol - I am OK with it.
I know this is not an option for most people but I painted over my exterior teak with a color that is close to teak. I just got tired of the time I was spending fussing with it. My next boat won't have any exterior teak. I have better things to do with my time.
I just don't think a bunch of external teak necessarily makes a boat look better...that's just my personal tastes though. I certainly respect those who differ in opinion.
