Same question about underbody. I am in Massachusetts and all LC100s I looked at had fair amount of rust. I think about talking to some garage to allow me to use their lift and put rust oleum or some other primer/paint on the rusting parts. Any suggestions for materials? Any gotchas? I definitely do not care how it looks from under the car but do not like this rust at all.
I have this same issue with my 2001 LC. I brought it to a mechanic a couple weeks back for an unrelated brake issue and he pulled me out of the waiting room just to show me the severity of the rust on the underbody. I have only owned this truck for a year and a half. The PO must have never washed this truck after being on salty roads.
I called a couple body shops to get some ideas and they were pretty much at a lack of words. Any ideas anyone ? This rust is pretty bad. Anyone know anything about sandblasting it or coating it ?
