i'm new at this.what does density mean i see 2lb 4lb 6lb? thanks

The higher the number, the higher the density equaling stronger flotation.

How well does this hold up to exposure to water? Applied to the bottom of a boat rear swim platform, for example, to reduce noise?

Not good exposed to the elements.
