Yes. They did warn me but that's the only hope I had today to get her back on the road for tomorrow. I used lots of PB Blaster and 200 Grit sandpaper. Came out smooth as a baby's bottom and no scratches or warps on the head. Then finished it off with 400 wet sanding. Checked for straightness and warping with true straight edges and was perfect to the eye. Wasn't having a ton of fun doing that, I must admit. A belt sander would have been much easier. She sealed up like pores in pigskin sitting in a mud bath. No oil leaks, coolant leaks, and no oil into the coolant. And car idles soooo much smoooother now. Starts fastest it ever has. Yes, was a little bit of a gamble, but I only had today to go for it.

Otherwise, was gonna be off to Carmax.
