I had one bad experience with Wipe Out in that one of my cans was not pressurized. I called the "home office" and the gentleman that answered was the head dawg and was as nice a guy as you want to meet...very attentive to my problem and took care of the issue pronto. Kudos to that gentleman! In the process he made sure to also provide me with a couple of applicator spouts and they made all the difference in the world. Great product and I no longer let it sit a couple of hours. I schedule things where I let it work all night long and it usually takes care of business the first times except in stubborn cases like my Sakos, which are like copper mines. Great stuff and great people to deal with. A+++++
