I currently have zero rust. That was a selling point when I bought this vehicle. Part of that is probably because I think the previous owner did not fix any leaks for about 250,000 miles. Every thing underneath the vehicle had a nice water and salt proof coating on it when I bought it.New window runs would be a good project! Personally I'd invest some of that cash into a spray gun and compressor and do some rust prevention.. pneumatic wire wheel all around the frame and axles to get any surface rust down to a minimum. Then coat with some Corroseal and a top coat. You love the beach as much as I do so you could also use your spray gun to apply a fluid film or wool wax.
I have thought of that. I am about to redo the weather stripping.Weld the sunroof shut or make it so it works and seals.
Sound system is definitely on the list. What did you spend to get the leather redone, if I may ask?Sounds like you are really covered. There are some other small items that others already mentioned.
How is your interior? This is not mechanical, but one of the best refurbs I did was new leather and seat foam. Made such a huge difference in how much I enjoy driving the vehicle. That and a decent sound system.
