I dont like to have water in my hull... But I did see someone made a reservoir out of foam, or pool noodle, for the puck, where you add water to it... I am lazy, I just like to get going, so I use goop.
Mine has not popped off, in my previous yellow kayak, it just took a puddy knife to pop it off. In my current green kayak, I cannot get the puck off, I was gonna move it... I am sure with more patience, it can pop off. I only mention color, because I am not sure if it makes a difference in relation to heat. I know that my green kayak gets HOT sitting on my racks in the sun, maybe the puck fused to the kayak...
