Title: Did not work on my 1986 Subaru Brat
Review: I had a small head gasket leak. I tried a cheaper product with copper fibers first. That worked for a day. I flushed out the entire cooling system and tried Blue Devil. That lasted for 2 hours. My small leak is now a bigger leak. I'm wondering if the problem for users depends on whether or not the engine block and heads are made from aluminum. I would not buy this again.
Is the review positive or negative?
