I used Semco Teak Cleaner & Brightener first & then sealed with Honeytone - Previously the "Natural" had been used - I found that gave a "yellowy" finish (as can be seen on the open hatch door & gunwales. I prefer the richer tones of Honeytone. The teak on my boat now stands out from all others in our marina. I have researched the subject & found nothing to beat or even match Semco product
