I removed and stripped/sanded all the exterior teak from the 19. I opened up an old can of Cetol and it was still fluid without any crust on top. After straining it the nesh had very little clumpyness in it so I thought I would use it. Well, after 30 hours in a 70° garage it's still wet. Looks like I'll be cleaning it again and buying a new can. 🤨
