Hi all, I'm about to replace a water pump on a 96 Saturn SL2 (I know, it's not Fiero-related) and I would like your input on a product called copper coat/copper gasket spray tack. (Or whatever it's called) I have always used Permatex #1 or #2. (Thick brown goop) I watched a YouTube video where a guy swears by the stuff and has never had a leak using it. Anyone use this type of sealant? As an FYI I have also seen this stuff at the auto store in a plastic bottle with a built-in brush. Maybe this version is called Indian head shellac? Ok, enough. Your advice on water pump sealant? Thanks, Kit
For more than 40 years I've used Permatex® Aviation Form-A-Gasket® for jobs such as installing water pumps. I put a thin layer on both sides of the gasket. There might be newer products out there that work well, but I'm not changing what works for me after all this time.

any sealer on some to most types of gaskets can cause gaskets to fail now or soon. Many people use way too much RTV and related sealers then "boogers" can plug whatever and causing oil or coolant problems. search RTV for more.
For "plane" paper I use Permatex High Tack. Keeps gasket in place to mount the part and seal w/o problems. Available in paint cap can or as "spray paint." Spray, dry a bit, and install. I did use Avaition or Super 300 but High Tack spray is very easy, little clean up, and does work. Just use cardboard as backstop and throw away when done. Flip can over to clear the top and leftover sealer will last for years.
Ok guys, thanks for the advice. I start in the morning. I ended up getting Permatex High Tack Sealant in the metal can. (With attached brush) Forgot to mention the Saturn uses an o-ring gasket rather than paper. Kit
Water pump job on the Saturn is now done. No leaks. For being front wheel drive, it was not all that hard to replace it. Thanks for the sealant advice. Good stuff. Just a little stringy after a while though. Kit
