I bought this product to make a fairing compound of the consistancy that I required. It was easy to mix up and easy sand after it cured.

Very high quality like any of the West System's products I've had the pleasure to use. You can mix it in any amount to get the consistency you need (from honey to peanut butter), and it will cure into an easily sandable mass. I used it with G-flex 650 to spackle some exterior painted woodwork that had developed a rough surface due to weathering. Sanding was easy with an electric handheld random orbit sander-can't see the repair after painting. I followed the directions that came with the epoxy and it worked well.

I bought a used 2015 Sea-Doo GTI 130 that had some spots worn through the gelcoat in the hull and a few dings topside from bashing into the dock. This filler works great for filling in holes the gelcoat with epoxy resin.
