Ok here goes. I own a Mobile Detailing business and I was contacted by the decorator for my local hospital. She found me via my wife who happens to work there. Anyhow she told me that a Mobile Detailer used to take care of all of the signs on the property for many years until about 5/6 years ago when her budget was cut for the work. They have not been touched since. Well she just got new budget approval for them to be done again and I am fairly sure the job is mine if I want it. Heres what I know (or rather don't know); they are chalky looking green paint and I can rub my finger on them and it leaves a shiny wipe mark, she has no idea what type of paint or clear coat is on them, she has no idea what products or technique was used to keep them up years ago, she has no way to get in touch with the former detailer (he retired and moved away) to find out. There are about 25 signs varying in size from 30' tall down to the small one in the picture. Has anyone ever done anything like this? What process and/or products did you use if so? Any information would be great as I really don't want to bite off more than i bargain for.
