## Customer Reviews

### ⭐⭐⭐⭐⭐ Affordable and good.
*by T***R on March 7, 2025*

Use this with their microglass beads and it's much cheaper than most fillers. Sands easily if you mix it to peanut butter consistency. I used with WestSystems 105. Great fairing compound. Downside is that you have to mix two different powders which takes a few more seconds.

### ⭐⭐⭐⭐⭐ good quality
*by B***S on June 28, 2025*

good quality, good price. i use for filling small areas, and fillets. make sure to mix well with resin before adding mekp.

### ⭐⭐⭐⭐⭐ Works great.
*by K***R on September 8, 2023*

I find this stuff works great mixed with some Max Bond epoxy. Mix up the epoxy according to the directions and add some of this stuff until its like peanut butter and it makes a glue that, as far as I can tell, never comes apart. Add a little wood flour to the mix and you get a nice filler material too. This stuff is pretty particularized so its best if you use it outside or at least in a garage with the doors open. Not sure what happens if you breathe it in but I'm sure its not a good idea. If you are outside be careful, a good breeze will empty the bucket for you and it'll all be gone. Great product.
