This Alex really let me down on my last project, it has been cracking like hell. Had great luck in the past but wouldn't risk it again

Same here. Worked great 3-4 years ago, but tried it again last month and it was awful. Consistency was all over the place and cracked like crazy once dry. Maybe they changed something in the formula recently?

GE Silicone II is flexible and can be used anywhere there's going to be moisture or movement.

My favorite is Polyseamseal. Done deal.

Agreed that silicone is the way to go for areas with moisture, but they can be more of a pain to clean up since they're not water soluble. Acrylic caulks can be cleaned up with water before they're dry so it's a bit more forgiving if you're not a caulking pro.

In theory, both should be good for areas with movement but I've heard silicone holds up a bit better over time.
