This product was phenomenal. It helped me take a whole week off of the time needed for my tumbles! Highly recommended if time is a concern!

. Breaks down too soon. no trace after 36 hrs of tumbling.

its grit all 60/90 grit is the same

I ended up using this as a stage 3, seeing I ruined 3 stage 4 tumbles,
