I did but it didn't budge much. Being frustrated with the soap and polishing debacle, I decided to stop while ahead and wait to finish it on a clear head. Weirdly on setting 9, it's hard to notice the difference in blade gap. It's setting 1, where it's most noticeable.
I kept it on setting 1 when I straightened out the Slims so I could check my progress. It isn’t meant to budge much, took me a half hour to finish mine without damaging anything. You’ll get there. I’d leave my caps and doors alone, the more you use and clean your razor razor after use, it will be fine.
