Rust & Dust 

Term used at auto dealerships to describe supplemental "paint protection" and rustproofing that is sold during the part of the sale where the financing is arranged. It is a source of "back end" profit for the dealer.

"That customer was a total lay-down; he bought Slip & Trip (disability insurance), Choke & Croak (life insurance) and Rust & Dust"

Rust&Dust

Research and Development (R&D) that has gone sour and lost money.

Rust Dust 

The dust that spreads from a ginger person's head normally in strong winds or through scratching of the scalp. Be careful, rust dust is very contangious. If the small particles that constitute a ginger man's head spread on to another human it will instantly turn them ginger too. Also known as the ginger disease.

John stop spreading your filthy rust dust around, you'll infect us all!

Rust Dusting 

Grating a frozen poo.

All the scent off poo, with none of the evidence.

On my last shift work before moving away. I stayed back late and did some rust dusting in the bosses office.
