I used your K Seal for the first time yesterday, 8/30/17. Was helping a person with Hurricane Harvey when a kind person said, “I think your vehicle is losing coolant” – sure enough it was. Bought your product at Wal-Mart. Followed the directions and it worked like a champ. I will certainly recommend your product – it works.
Follow-up email 8/31/17:
The leak of coolant was coming from the top, right-side of the radiator. Had to pull a trailer today with my truck. Checked the radiator before and after and the radiator was sound – no leaks. Thanks again for a quality product.
