Don't know about Pacific Fiberglass glass work, but don't have them do any mechanical work. They are not good at that. It took them like 12 hours to pull my prop because they didn't have the right prop puller. Instead of buying the right tool, they beat on it with sledge hammers and heated it up for hours on end. Then after they put the boat back in the water, I had some vibration. They avoided my calls. Would not pick up the phone, wouldn't return my calls.
The paint touch up they did was decent, wouldn't say it's perfect, but good enough.
You'll hear a lot of people recommend them, but again do not have them do mechanical stuff. Oh and btw, they charged me for all those hours of beating my drive shaft.
