I've used many of the Sikkens products inside and out, don't cheap
out, it goes farther and lasts longer.

My hot tub with cedar surround came with a Sikkens Cetol 1 treatment factory
applied ... I went out and got Cetol 23 and applied it over top, and 2 years
later the tub looks better than factory fresh despite the weather to which
it's been exposed (southeastern Ontario ... we get it all). Not inexpensive,
but exceptional value for money. If their other products are alike, I'd
recommend them highly.
