Dean Markley Love Potion vs. anything else for fretless?

[golem]

Just got a new bass, lightly used Yamaha TRB 1005F, my first fretless. The strings will be GHS groundwound (Brite Flats), the former user had roundwound coated I think. That left marks ...

Wanting to take care of the Rosewood fingerboard, I have now used Dean Markley Love Potion #11 Deep Cleaner just once. The colour went from faded light to a beautiful darker brown with more texture and the marks evened out a little bit.

Then I wanted to use Dean Markley Love Potion #15 Fretboard Saver, maybe after another DM LP #11 Deep Cleaner.

I'm not sure I can get Bore Doctor or Fret Doctor here in Europe, but was hoping somebody had any experience with these or similar products.

On a later occasion I might polish it with very fine sandpaper to get it 100% smooth again, but that's for later. Also a possible coating or hardfinish is a thought, but first I want to try the pure Rosewood feel and sound.
