I would also top off the case with acetone to make up for evaporation. I could only soak half of the stock at a time, but that is certainly faster than wiping it down in an open and constantly evaporating container of acetone. I filled up one half of the case with acetone, placed the stock in it, and closed the case. So I pulled the foam out of one of mine, and saw the recycling symbol with a number 2 in it! :2thumsup : censoredĪs I was browsing the web looking for something that would work, I glanced over and noticed my hard shell gun cases.

Most commercially available storage bins made out of PP or HDPE happen to be 2 - 3 inches shorter than a stock. I could not use a PVC pipe, because acetone destroys PVC. I found a method that worked, my next challenge was to find a container large enough to submerge the stock. The container I used wasn't large enough to soak the whole piece at once, so I soaked either end in it for 24 hours. I tested acetone with two of my P14 upper handguards and the M48 handguard with an acetone soak. Most storage bins are made of PP, so I already had a few laying around. A number 5 in the middle is polypropylene (PP), while number 2 is high density polyethylene (HDPE) The little recycling symbol on most plastics will tell you what kind of plastic it is. Apparently, it is used to make meth too.ĭoing some research, I learned that polypropylene (PP) and high density polyethylene (HDPE) are acetone safe. Walmart will not sell more than 1 gallon of acetone at a time. But working with acetone has some challenges.Īcetone vapor is not something you want to be breathing for any significant length of time.

Acetone dissolves cosmoline, and dissolves it quickly.
