Great stuff to thicken resin, exposes, etc. Helps to glass out the product, makes it harder as well, but make sure to bring one’s A game when sanding, similar to sanding granite, Don’t breathe it in when mixing, wear some good PPE.

### ⭐⭐⭐⭐⭐ As per other reviews, they sent the quart and I had to return it.
*by J***R on March 22, 2024*

Nothing wrong with the product, it's cabosil. Unfortunately the seller sent the quart size and not the gallon size, seems to be a repeat issue. Thanks to Amazon's quick Staples dropoff return policy I had the correct size on the way to me the next day. A nuisance, but I wasn't in a hurry so it was fine.
