Great thickener for JB Weld!!
Excellent product! I use it to thicken JB Weld! The plus side is that it actually strengthens JB Weld! Also, great for epoxy.

Its great but it takes a ton of it to thicken resins
As far as quality and end results its great. My only complaint is that it takes a massive amounts of this to thicken to a putty. Its not a quality thing, its just something you need to know. It took about a third of the quart to thicken just 4oz of resin to a putty consistency. For smaller jobs this may be a non-issue, but when its something bigger, like a boat in my case, it would cost a fortune of it to use this for all the areas I need to use it for.

Good stuff don't inhale it.
Works great for thickening up fiberglass rosin when you don't want it to drip leak or run. Use it on vertical body work. You might want to use a mask when using it, it tends to fly around in a breeze.

Thought it was empty
Container was so light I thought it was empty so I took a video while opening it. It was not empty. I’m not sure why I bought this so I can’t say much about it except that I received it.
