3m Super Duty

[L&I Detailing]

Anyone know how gritty 3m`s super duty is? I used to use it all the time but was tired of using a brown compound on white. Today a client asked me to use it on his freshly gel coated gunnwales and I followed it up with finesse it and it was really nice.

Ive been using 3m imperial a lot lately which I like and I know is roughly 600-800 grit.

Also in relation to the duragloss series how gritty is their 561 and 501?

Just wondering

I always thought it was more than 561.....
