What do I use on my teak?

[cdlong]

I have a 1975 Cub Cadet garden tractor and on the posts they always want pics to guide you in repairs. I forgot, so here's some pics of the teak. I also have a pic of the stuff I put on it last. I am concerned about sanding because I figure I need to remove the teak to sand and th Po had a bad habit of using marine silicone sealant with adhesive to fasten everything. I have several spots near the rod holders where I had to remove them because they got broken into pieces.
