Your prep may take a month but the painting will only take a few hours with
a good airless. I have an old Binks setup from the mid 80's, still runs
like a champ.

I may not know enough to ask the right questions - but some of the sites
I checked - "airless paint sprayers" seem to have air hoses attached to
them. What am I missing? I have a Sears compressor and a spray gun that
I used to paint a jeep with pretty good success. I though an airless
system would be one like a Wagner with just a power cord.
