I used this to as bedding material for Pillar bedding a rifle. It was my first time using this material & was a little difficult to work with, compared to what I had read about it & compared to other materials I have used in the past. It was very messy, seemed to get everywhere once you got some on your hands, which seemed impossible to prevent. Next time I will use rubber gloves in layers to peel off once gets messy. It also took very little overflow that was not cleaned up to try to "lock" the barreled action into the stock. Just what oozed up after 3 clean ups along the barrel, needed attention when I went to remove it. Had to use small wood chisel to cut / break the material loose on top of the stock edge. It is very tight fit which was the intended result, so I liked that.It was not that it did not function as it should have & according to mix instructions. However for the purpose I was using it for, it was more effort than expected. I would use it again & feel next time it won't be as bad now having some experience with it & how it acts, flows & is to work with.However, I feel I like Score High bedding material better & it is easier to work with.
