cossiestu. Must have been a bit of a shock to find that amount of rust!! I am so thankful that the first owner before I got my Saff had the waxoyle treatment done and 25 years later still no rust. My advice would be get it done by a good reliable bodywork guy. If you are not 100% confident of your own welding skills it could be a real nightmare.I have always believed in certain jobs need to be done by specialists and providing your funds will allow it get it done properly and you will never need to worry about it in the future. Good luck with what ever route you decide to take.
