Imho, the original gel is tougher than a redo. The only reason a large area would be spayed like that is if the color was being changed. That is an awful lot of blocking and polishing to do the entire bottom. That's a $5,000+ job.
They're probably going to spray the small areas to be repaired and should be able to match really close to the original color.
How old is the boat?
I don't know of any guys down in that area, but I know of three up here in the SF Bay area.
Good luck.
