Rich,
Haven't used the Pig Snot yet, I want to research it's affects before I start using it. I plan on using it on the underbody and wheels wells.
mbtjc,
If blue is coming off when you polish then it's definitely not a clear coat, thats surprising! Sounds like the cars in good shape and just in need of a little lovin, good luck and I'm sure whatever your decision it will look good!
