Living it great upstate NY we get a lot of snow. And that means a ton of salt on the roads. This has caused the rear of my frame on my 06 LR3 to develop surface rust around where the spare tire sits. To stop the rust I tried a product called chassis saver! This stuff goes right over the rust all you have to do is wire brush the rust first. It's not that bad in price and all you have to do is brush it on. Only time will tell but I have seen great reviews for it.
