I purchased a 5 gal container of Berrymans Chem-Dip about 2.5 months ago. I followed all storage directions, stored it on cardboard, and the container recently started to leak. I noticed a previous entry to the same effect. I am sure we are not the only ones this has happened to. I believe the integrity of the containers is compromised by purchasing pails with a rolled edge vs. a welded lip. Rolled edge containers are cheaper to produce, therefore, also to purchase. I work with hazardous chemicals and waste on an everyday basis. I see this a lot with rolled edge containers. I am a safety specialist. I paid $125 for 5 gallons of Chem-Dip. For it to only last me 2.5 months, because of the integrity of the containers, is ridiculous. You sell a great product but this is unacceptable.
