Review on LubeLocker Dana Differential Cover Gasket by Dave Tapia

I wish it would perform as advertised but it doesn't, at least not on the Spicer stock aluminum cap with raised sealing surface. The embossed logo seems to leave a gap that allows for leakage. I wish the manufacturer cared less about the ego and more about the sealing. Look at the picture, look at the spaces between the letters. I want a refund but need to put a truck on the road so use sealant and write off $25.
