Wayne Harris says, "This stuff works!"

This stuff works! I have a 2002 Grand Am with over 160k miles and one day the steering rack sprung a leak. Not a drip-drip, but a stream of fluid shooting out the driver's side of the rack, emptying the power steering reservoir into a 3-foot wide gusher blasting out behind the tire. While shopping for a replacement rack online, I found people claiming this stuff works. I bought 2 bottles. The first bottle pretty much streamed out the gaping leak, but must've done something because the second bottle stopped the leak! Wow. I'm carrying a third bottle in the trunk, just in case. Much easier (and cheaper) than replacing the rack. Time to look at some other Lucas products! Wayne Harris - KY, Alvaton
