I've started using Scott multipurpose shop towel that was recommended somewhere on the web for taking off/polishing in Monocoat. It works fantastically, doesn't leave any lint or dye behind.
Halfords sell it by the roll if you want to try it, I get it from Amazon now, I think it was £32 for 10 rolls. - I only use it for finishing, everything else I use the big blue rolls you can get pretty much anywhere.
