Perfect for adding to Bondo for extra strength. As a taxidermist, I add it to Bondo to make thinner ears in the animals that I taxidermy. It does a great job.

Strands too long, does not mix well with cement

Absolutely what it says. I ordered what I got. I made a mistake thinking it was 5lb but it was actually 4lb. I am so sorry. The cut is good and the weight is correct. I will be ordering more in the future.
