Dear mid-60s Buick
"can't ever love your cars enough" types,

. . .
It's all Walt's fault! . . . .

I went back to my earlier posting to see if I could confirm Walt's information about bumper jacks in my CD copy of the 1940-72 Buick parts catalog. I have tried to add search to that CD but it isn't perfect. However Walt mentioned it was in section 8 of the catalog. So I started scrolling down section 8. Not too far before bumper jacks I stumbled into this:

Back in the day GM was selling to its dealers something it called
GM engine shampoo! They must have been expecting their dealers to use a lot of the stuff since they could buy it in a 55 gallon drum!! Does anybody know anything about this stuff?
Curious minds want to know!!
Cheers, Edouard
