We did a large paint prep job this weekend for a local church in Montgomery. The walls were oxidized real bad and needed to be prepped before they could repaint. This wall was 20 ft tall and nearly 200 ft long. Scaffolding would have been expensive, a lift meant constant moving and repositioning, but our 30 ft trailer worked out great. Set up, washed a section and just drove down the wall as needed. Here's a few pics of the job.
