Great for creating a low sag epoxy mixture for filling areas where dripping epoxy would create a mess by refusing to stay where it's put.

Great stuff as are all of the West System product. However, wear a respirator when mixing. Silica is nasty stuff if you breath it in.

Easy to use, did the job well. Hopefully will last for years and years!

Makes a great filler for bonding wood parts together if used very sparingly in the epoxy. Do not advise opening the tube in a windy place. It is so light that it will blow in the wind like wheat chaff.

I used this mixed with epoxy resin to repair blisters on my boat. Even though it is extremely fine like talcum powder, it still mixed with the resin well and was easy to work out the clumps to form a consistent paste.

I use it as an adhesive filler in West System epoxy for joining wood parts.

Great filler. I used it to smooth out the fillet transition in a paddle I built.
