Read the the label in the directions and I quote "NOTE: Not recommened for use on head gaskets or parts in contact with gasoline." The reason why I can quote the label because I too was hard headed and thought I could use it. I bought some used it on an engine and now the engine. Is in the stupid a$$ hard headed users graveyard. When seeking advice on a RC site take in to consideration we know the answers because we already screwed it up by being hard headed. Use the products that were recommened to you when in doubt do it anyway for sh*ts and giggles.
