Hello Oppo

My wife happens to be substitute teaching as a paraprofessional today in a shop class. They happened to be demonstrating how to wax a truck. She messaged me if we should be doing this to our vehicles and I said yes but it takes forever. She said it looks soothing and wants to try it. I said okay and now I need to know what I should get for doing this. I have access to a heated building for doing this but no supplies. These are the vehicles in question.

They are outside all year round. They do get parked underneath the house at night. We never wash them.

Thank you everyone for any suggestions.
