So far I am really impressed with Dirko. I've used it to reseal an engine sump pan that was leaking. It was easy to apply and spread, has stuck well to the degreased surfaces and most importantly is keeping the oil where it should be. Next time I need to replace a water pump or thermostat I'll use it to reseal those housings too.
