Clean, recaulk bath surround

I've had some mold in a few areas around the bathtub for months.
I tried industrial cleaner, vinegar, baking soda, alcohol, pumice stone, Magic Eraser and
then finally Clorox Clean Up w bleach. The next day, there wasn't a trace of it.
Now I see some cracks in those areas. I was going to just put some caulk over them.
Then I see for some reason that's a no no - nobody ever says why! I did see a product that you can do
his...Permatex or something. Any experiences with this?

Dont do that, bet it's silicon caulk?

Need to remove and use newer siliconized latex caulk with microban!

It's Polyseamseal. Says: "Water based caulk provides a crack-proof seal...Watertight seal resists surface mold and mildew growth". Right :-(

As noted above it's best to cut/pull out the failing caulk and recaulk. You can buy a little time by just caulking the voids but putting a new bead of caulk over the old seldom fares well.

Yes, you need to remove the old caulk. New caulk will not stick well on top of the old and the old mold will be visible through the new caulk.
