I find :
Autoglym paste - shiny++, little cut
Peek - shiny, more cut
Autosol - shiny+, most cut
Usually just grab the autosol to be honest because its a good blend of defect removal and shine. None of these are going to remove much marking though.
Use 0000 steel wool with one of them and you get a nice slightly matted finish that lasts well. When its super shiny it shows every flaw, maybe not a good thing.
If the surface is really good the Autoglym one produces a really high shine.
I removed about 7 years of mild corrosion using 0000 and Autoglym on my LTS here..
