Just got a new muffler and when I took old one off the muffler gasket was a mess and took like 10 mins to get it all off. I have a new gasket but need a way to prevent the new gasket from falling apart. Coppercoat and permatex spray a gasket is all sold out in my neighborhood. What can I use as an alternative to make it easier to remove gaskets in the future? Can I use regular metallic spray paint? Could I use the gasket maker in a toothpaste tube and paint it on my gaskets?
