Sealing skirted bathtub

[phloaw]

There are plenty of tutorials for sealing/caulking bathtubs. However, my bathtub has a kind of skirting around its edge, as in picture:

How do I go about that? Should I caulk both edges? I plan to use standard silicone, would that be good for both? Is there any particular I should keep in mind for my configuration?

Note that the skirting is difficult to remove because it has a flange trapped beneath the tiles to keep it in place.

TIA

phloaw, good evening.

The trim fitted now can tend to leak over time.

if it were me, I would slowly and carefully remove the existing plastic trim and mastic, using a new sharp Stanley knife.

Then i would apply a quarter round ceramic tile bedded totally in mastic, something like the material below.

Ok, thanks. I suspected and dreaded that. I asked just in case there were a way to escape the bother of removing that strip.
