Head Gasket Sealer for 8 Cylinder Engines - Steel Seal

read reviews and thought i try it on my corsa d as water was being lost through water channels into the pistons and burnt through the exhaust system. haven't seem to make any difference and now got to replace gasket anyway , just cost me a extra 30 pounds for this rubbish .i also love the drama you got to go through for 30 pounds back . pay for reports and get a refund , just one problem the reports cost more than the refund . if they paid for the reports as well as the refund then would be a genuine money back guarantee .
