Great filler
I use West System products exclusively when doing marine fiberglass repairs/modifications. There are many different filler options, so choose the one that best fits your needs. Mix the resin, add the filler and mix to your desired consistency, then apply. For me, usually similar to mayonnaise works best. Drying time will depend on your choice of hardener and if you've adjusted the resin/hardener ratio.

Works good
We purchased this to fix our RV fill in a soft spot. First off it is easy to mix in with the kit but it does set up fast! So you need to be ready to go to pour when you mix it. It worked great for what we used it for, has been fixed for well over a year now and still holding strong.
