Review on 🔧 West System 407-5 Low Density Filler 4 oz: Perfect for Lightweight and Strong Repairs by Jeffrey Mosqueda

Very high quality, like all West System products I have had the privilege of using. You can mix it in any amount to get the consistency you want (from honey to peanut butter) and it turns into an easy-to-grind mass. I've used it with G-flex 650 to "fill" some exterior painted woodwork that has become rough from the weather. Sanding was easy with a handheld electric orbital sander - no visible repair after painting. I followed the directions that came with the epoxy and it worked fine.
