Bars Leak Head Gasket Sealer

RE: '04 V70 NA. I just wanted to report and I guess endorse Bars Leak "Professional". Although I don't know the size of the leak, I guess I had a pretty good hole in my head gasket. Plenty of steam out of the overflow bottle and enough pressure built up to blow off the top radiator hose. In any case I decided to give the $50.00 Bars Leak "professional" a try. After a pleasant call to Bars Leak question line, I flushed it and followed the directions. I have to report success. I am only 4 days into it, but all seems fine. I haven't tried highway speed yet, because package indicates several cycles of heating and cooling aid it. I will report if it fails. They have several less expensive head gasket products, but I didn't try them
