## Description

West System 407-5 Low Density Filler 4 oz: desertcart.com: Tools & Home Improvement

Review: Great filler that is easy to sand - West Systems make the best epoxy products for my outdoor wood projects. This filler makes it much easier to sand. I have used West Systems products for years.
Review: Excellent fairing compound. - This fairing compound mixes well with epoxy to thicken the epoxy to a orange-red colored goo, the viscosity of which depends on how much you mix in -- from a soup to a peanut butter type of consistency. It is easy to trowel on to shape whatever it is you are forming. Sands much easier than fiberglass, but still strong. The only improvement would be if they could make it into a lighter color, or better yet, white. The red-orange color is bold and takes several coats to completely cover over with white gelcoat.

### ⭐⭐⭐⭐⭐ Top notch!
*by R***A on June 2, 2025*

I had to do some fairing and filling of a keel and rudder. It worked great for filling. Not great for fairing. Very good product, be sure to use whichever product (403, 405, 407, 410, etc) is recommended for your use, it makes a big difference in finishing! I definitely prefer West system products, too quality stuff for boat work!
