Review: Best gasket maker ever. - Best gasket maker ever. 10 minutes you're ready to go. No overnight waiting or hours. Works right every time. It's pricey but worth it.
Review: Excellent - This stuff sticks better, hardens harder and faster and seals better than the standard stuff. If you need to put back in service immediately this is what you want. Its strong enough I have seen it repair a cracked engine block water jacket on a boat whereas the engine is junk otherwise. It can holdback coolant pressure!!! Excellent stuff
