Surfix One-Step vs. Watco Clear Danish Oil finishes on furniture?

[Scott in Bend Oregon]

In the past, I have been using the current version of Watco Clear Danish Oil and have been very happy with the process and end result.  I am out of Watco and thought about trying Festool Surfix General Purpose One-Step Oil on my next project.  I am certain that many of us are very familiar with Watco.  But, has anyone here had firsthand experience with both products?

I did a search here on Surfix and Watco without success.  Your help would be appreciated.

The project is freshening two very dry 45-year old oiled walnut speaker cabinets and they do not require a heavy duty or exterior-grade finish.

FWIW, this reply will be relevant and irrelevant at the same time. I have used Watco Danish & Watco Teak on a teak table outdoors. The table has a cover on it all winter and during any rainfalls. The Watco Teak seemed to last a little bit longer than the Watco Danish but not much longer, the table still needed to be refinished 2-3 times per season. I tried Surfix Outdoor oil and 1 treatment will last for the full season. Does that durability advantage also apply to Surfix One Step? One could assume so, but I don't know because I've never used One Step.

The speakers aren't JBL's per chance?

The speakers aren't JBL's per chance?

Yes, JBL L100 Century.  Purchased new in 1973 directly from the JBL factory.

I have a pair of L100A's myself that I purchased new in the early 70's with only 6 serial numbers seperating the pair. Do you have some good sources for parts?
