    Can you be more specific on the products you are referring to? Is it a spray fairing compound compared to a powder load to thicken a resin?

    One is a pre-mixed, thickened resin; you add a bit of catalyst, mash it up, and spread it on.

    The other is a powder that you add to the resin of your choice (usually epoxy) to make it thick enough to hold its shape when you spread it.

    Epoxy plus microballoon filler is the usual choice for a boat. The polyester-based car body fillers don't hold up so well in the marine environment.
