              Comments about Permatex Copper Spray-A-Gasket Hi-Temp Adhesive Sealant (10 oz):

              I used this based on another recommendation, for a water pump. Big mistake. There is no director tube or spray pattern. You get a circular thin even coat all over the area you are targeting, and then some because of the overspray.

              On a water pump housing it went on the mating surface where I wanted it, but I cleaned the product out of the water passage and off the blades of the water pump. You don't want small pieces of gasket material plugging up the vanes in your radiator.

              More overspray was on the engine block itself. Which was ignored since I don't have a show engine.

              I'll go back to applying the tube version which has no time consuming post application and pre-assembly cleaning or part masking requirements.

                Used to put gasket on new water pump for 2002 Saturn SL1. This item was recommended to me by a auto buff so I figured I'd try it. This is the BEST product out there! Makes putting on the gasket and holding it in exactly the right spot easy as pie! I highly recommend this and will use the rest of the can on any other projects like this that I have!

                  I always use this gasket sealer on cork gaskets. It helps to hold the gasket in place and prevents oil soaking thru the cork gasket

                      A:

                      Hi Barnabas, it's a great question! This application depends on what the gasket is made of. The #80697 is specially formulated to assist with only filling 10’s of thousandths of inches for proper head gasket sealing only. The #80064 is formulated to apply an outer coating to cork and fibrous gaskets like thick paper, to extend the life of the gasket.

                    can use this product on a used head gasket to reuse it>

                    • A:

                      That would be pretty much like reusing a rubber. A head gasket is cheap, but the time it takes to replace it is expensive. Why would you want to take a chance reusing a HG?

                      You shouldn't use a sealer with a HG anyway.
