I have a 'teakey' ... all decks, etc. are teak.
Have been using Semco "natural' for about 8 years, keeps the deck 'tight', non slippery ... allows the wood below the Semco to become wetted (traction!!!!).
If you retard the UV destruction of the surface cells you will have very little 'erosion' of the teak as you get when the deck goes 'gray'. At now $40/ board ft. for quality teak, Semco is cheaper. I mix 1/2 'natural' with 1/2 goldtone. Once every 2 yrs. I strip with diluted TSP to rebuild the natural color ... since the teak isnt much degraded by UV the TSP 'etch' is very minimal.
Only downsides - recoat each 6 mos. and it will eventually 'transfer' to the soles of your deck shoes.
AT one time I used to mix 1/3 Semco, 1/3 Teakwoner, 1/3 Thompsons water seal ... no diff.
