Thanks for the help, your thinkpad turned out great. Just one question, did you disassemble the screen panel or just applied it?

So i bought a very cheap used x200 off the internet, its in overall good condition with the exception of the lid, it has some smudges that look kinda like fingerprint oil, but i had no luck removing them with a dry cloth... Is there a proper way to clean the lid? I was thinking about trying isopropy...
