The job went mostly well. The before & after was not dramatic, as the building was not extremely dirty.
My crew did a mediocre job rinsing the area around the work site resulting in some 1% leaving spots on the aluminum sponsons on a pontoon boat nearby. Going this weekend to inspect.
I have a lot of contacts in the marine industry in that area. I worked as a deckhand/captain for almost 10 years in various locations worldwide, on charter boats. I know some boat detailers who can remedy the problem. I want to see the effects for myself
