What I would do, sand to the desired smoothness, and then apply a two part teak cleaner like Snappy Nu Teak. It cleans out the pores and bleaches the wood to a natural sanded color. If you sand more after that you may sand back down to dirty wood and have to repeat the cleaning. The results will amaze you. Then finish with Sikkens Natural Teak, 1st coat thinned 10-15% for penetration then a 2nd for color depth. I then finish with 3-4 coats of Goldspar Clear Gloss (It has the best UV inhibitors)
lightly sanding between coats. This was my process on my last Catalina 30 and lasted for 4 years with out retouching. Then I sold the boat to buy my J30. Worked for Me!
