A mere 4000 sq ft, classic cars from front to back. Friend of mine poured the floor a couple years ago and recommended me to polish it. Floor still has a great shine, no stains. Gonna be easy but... What should I charge? A weekend with the 36 coup? Or maybe a spin in the 67 Charger. Maybe a nice drive through the country in the 42 chevy flatbed... I don't know guys, whats a fair price?
