I agree 100%. Good advice. I used the blue one. I'm thinking it was 60 grit. It worked awesome for grinding the lip on my closed top when I was fitting my lid. Conforms to a round surface better. Don't use a hard disk. I ruined my last drum like that.
I used the blue one the other day under my 4wd Dodge. Grinded the heads off of two hardened steel 9/16" bolts when I was swapping out control arms. The blue discs are bad to the bone. Got mine at lowes.
