While I can find a number of sealers around, my concern is with the temperature that the piece may be subjected to. I really don't know how hot the valve cover gets so I want to be on the conservative side. Put differently, I don't want to be sitting in traffic in July, look down and see the sealant flaking off!!!

Any advice appreciated.
