you better damn sure spray it very evenly as just a little too much and youll have water leaks. I dont think it actually does anything for a honda gasket as they are always coated. I would like to see if anyone can prove that this stuff does a damn thing on a honda engine. What about the spray that gets on the gasket between the sleeve and block does this wash off or otherwise get into the engine and radiator? I think this **** was designed for domestic cars with their fiber or paper gaskets and solid deck engines.

 

dont use copper spray.. it's prone to not being able to seal against coolant.
