Golden Care Teak Shield

Will this work on teak patio decking?

what is difference between this product and Golden protector? Do you need to use both and how often do they need to be reapplied?

Can you apply this teak shield over a teak sealer?

would this work on a very pale bleached oak coffee table (indoors)? I am concerned it will darken the colour of the raw wood or turn it orangey
