Never heard of it ! Well when i first heard of it i thought "thank god" cause it can do many things (i.e. adhere to hard to stick surfaces being varnish, lacquer, glass, pvc, etc). Also it aint a two pack stuff which is great again. Also the most amazing thing about Zamix Coverseal is it can be overcoated within one hour of application and its oil based and it can be used inside & out.
