Great gasket sealer

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

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.

      I've been using this for years on older engines where the gasket surface aren't perfect. It helps seal the imperfections on gasket surfaces for no leaks. All you do is spray both sides of the gaskets and install it.

        Does exactly what it says it will do, I use it on the head, cylinder base, and exhaust gaskets when I am rebuilding jetski motors. Note to a previous reviewer, read the instructions, it says to apply to gasket and not to spray it in engine compartment.It also says to mask areas you wish to avoid getting overspray on. I just spray both sides of the gasket wait for it to dry and bolt er up .... No worries about gasket sealing down the road. Plan on using this on every rebuild I do to avoid issues.

                      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!

                            Happy to assist you with your question Bob! This can of spray gasket (Part No 80697) can used to possibly seal a leaky cam plug. The deciding factor will be how bad the leak is. This Spray gasket is meant for minor surface irregularities, and a supplement to a gasket such as a cork gasket. For a leak like yours how good this product will work depends on how bad the leak is. When applying be sure the surface is clean of oil and dry as possible.

                            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.

                            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.
