Alright after some gathering of information and making my list and checking it twice I've decided in the next 2 weeks I will be starting on the adventure of taking on my rust.
I've managed to find an angle grinder that im going to purchase a wire brush for and I am going to get some gell the turns the rust into Iron Phosphate.
I'll get the heavy stuff off with the grinder then use the gell on the other stuff and after that all dries (will take about 24 hours) I'll use this spray on undercoat to cover the whole under body to protect it. I'm also going to take a look at my trunk and under the hood because I did notice some spots in those areas also.
Expect pictures when I get everything going
