I put out solicitations on Thumbtack for someone to pressure wash the empty engine bay of my Porsche 944. I was surprised to see John Bowers respond as he has a local reputation as an excellent "large scale" painter.
What went well? Everything! John's reputation is well deserved. First, he is an easy individual to work with. Secondly, even though the job was just cleaning an engine bay, he did it in the most professional and meticulous manner.
If I had any painting job, John would always be my first choice.
