Not trying to start a panic here, but has anyone had any trouble yet? My local Airgas is on 50% allocation. Bring in 2 for exchange and you are going home with one empty. Not a big deal since I only need one to keep going, but I have heard that other areas of the country are getting hit harder. And my rep said they are not sure how things will be looking in the months ahead. He said it depends on how many guys he can convert to propylene for cutting. If you haven't gotten chummy with your rep yet, maybe now is a good time. It may be a good time to get that bottle filled.
