What are the instructions for using the Step 5 polishing gel? The instructions are clear except for the final step.

I didn't use it, there were no instructions, Sad I know. Sorry

Does the Media contain plastic?

I don’t believe so, also stock up on belts as they don’t last very long anywhere between a few days to a week or so. Tumbler does a great job though.

Where can I purchase just step 4 polishing grit I don't need all the others

You should be able to find each one separately on Amazon. I have gotten step #3 individually before (because I'm clumsy and dropped a whole bottle of it on the ground).
