Shower sealing recommendations?

[Weichl]

Hi - 1st time poster. I didn’t see this addressed anywhere else so asking here: the Melamine (?) walls of my 2011 SMB shower appear to be separating. Looks like the previous owners used regular silicone caulk but I’m wondering if that’s the best fix? (They used this on the ceiling fan and it was a mess…) Photo attached. Recommendations? Thanks in advance.

I think the photos will show up now.

Crazy suggestion here - but I used "gutter caulk" - white a few years back on my slide in camper bath - worked great. Before applying in your situation - I'd lightly sand the panels at the "45" degree area with a sanding block ? Good luck !

They just did a crap job of caulking. Grab a tube of good quality 100% silicone caulk in white, like GE advanced, strip out the old stuff first.

Thanks Ref - should I sand it a bit first or just apply the good stuff once the old crap is removed?

No sanding necessary, just remove all the old stuff and clean the seam, apply a generous bead of new stuff and run a finger down to seal it completely.

Thanks again.
