Works Great!!

I've always trusted Permatex Gasket Maker for my projects, and it hasn't let me down. It's perfect when you don't have a gasket or just want that extra bit of sealing confidence. Easy to use and holds up great. On top of that, Walmart shipped it out super fast, which was a huge plus. Definitely recommend!
