Thanks guys for your help!
I followed your advice and made sure to prep the area before diving into the project. I took a small sample of peeling paint to Home Depot and they were able to match it perfectly! Total cost for the job was $42.00 and I have a 1/2 gallon of paint left over
I have no doubt it will come in handy as I make my way around different areas of the bus. The color matched so perfectly I didn't even need to pain the ceiling, front or area by the "Emergency Door" decal.
I didn't worry about protecting the floor as I plan to lay hardwood over it once it's prepped.
