I ordered on bottle and that did nothing for my issue. I actually contacted the company not the person reselling this product. The price I paid here was crazy I also paid for expedited delivery well I was very disappointed. Talked to owner of actual company via of email and the. He actually called me directly great guy sent me two bottles free of charge but unfortunately the product didn’t work for my head gaskets on my 6.6. So it was a 10k bill to have them done with upgrades

The company I ordered through messed up twice in a row, but once messaging them and sending them a picture they made it right no hassle. Love the product and love how the company stepped up!
