I had the chance to go on a job this morning to see a demonstration with the QwikSeal. They were having trouble yesterday putting in a competitors product and after two hours of screwing around with it, they gave up for the day. I showed up this morning and within five minutes, they had the QwikSeal installed. Both the contractor and the county were extremely happy with the results and they asked me to make sure all of our distributors were stocking the QS-4, QS-6 and QS-8.
