I just found out that a 55 gal drum of the meth foam brush solution I use has increased $100.00 over last years. I called my supplier and he said THAT ISN'T NOTHIN. Wait until I get the next batch, possibly at the end of Winter or next year. He said they already have the prices and a 55 gal drum will be over $500.00. #1, is anyone else finding this to be true? #2, Is there such a system out there that would use the summer solution but after the brush is not used for a specified length of time it would purge the line with the meth but when it was being used it would use the summer soap? Does this make sense? This way as long as the foam brush was flowing the summer soap would not freeze.
