hey well this morning i found out my car is leaking coolant thru the thermostat housing,i went ahead and took it out looks like the seal was in bad shape though,well do they only sell that paper wth adheasive gasket only for it,also it is ok if i use indian head sherlock as a sealent??

 

I've been known to use RTV.

 

well thats what it had before someone told me to use indian head sherlcok would this be a good seal with it??
