I googled for inexpensive fix - i.e. a liquid product added to radiator that reportedly permanently repairs intake-manifold gaskets, head gaskets, cracked heads & cracked blocks. There are 2 products mentioned........"Thermagasket" & "Steel Seal".

Which one - - or another one - - is recommended ??
