I used the sweetwater. It is a dream to work with. I put it on at 5 coats 4mil each coat. Holding water like nobodys business. Silicone sticks to it with little prep, just a light sanding to rough it up, and there are place I did not roughing and the silicone sticks very well. Also suction cups stick to it.
Good luck
PS... Love all the colors it comes in too..
