Floor leveler on wood deck

[a70eliminator]

I need to build up a couple low spots on my deck where water tends to lay, I have a quart can of polyester resin and cloth for a topcoat, but what can I use for the main filler, these low spots are about 12" diameter and about 1" low in the center, I don't want to pour pure resin because it would take a gallon on each side, there's some pics in thread I started in boat topics, this is driving me crazy.
