Hey guys, I wanted to know if some of you have run into this issue and if so any recommendations on fixing it. There seems to be a lot of rust holes on the bottom area on the rear just behind the rear bumper. Seems on some spots where the rust holes are the previous owner put a mound of bondo on it too. I began kind of cleaning the areas of rust but not sure how i should go about fixing it.
I see no need to replace the entire tail panel. If that is the only rust on the panel, just have a body shop WELD in new metal in that area. Where it is located....pretty easy area to hide.
It means that once the repair is made, and the car is painted and reassembled, the area of the repair will be virtually unseen by the naked eye. The same can be said for floorboard repairs, for example. In contrast, a rust repair made on the top of a fender, or on the rear quarter panels around the wheel arch, can possibly be seen once the repair is made because those are more visible areas of the car. In my opinion, the amount of "hours" and "labor" that would be use to repair the area the original poster is describing would be quite a bit more to replace the entire tail panel than just to fix the area described.
One way would be to buy a cheap mig welder get some replacement metal cut it out and weld the metal in then finish the area you are working on like was said it is in an area that is easy to hide plus you have learned a new skill Welding patch panels its not the easy way but you will have gained another skill needed to work on old cars I have turned into a fair welder working on patch panels on my Maverick and it was a skill I didn't have before when it is done I will have saved a lot of money.
Hit the area with a sandblaster. It will eat all of the weak areas and give you a better idea of exactly how much "good metal" you have left. In the end, your common sense will prevail. I am in general agreement with Craig. Unless the area is extremely eaten out by corrosion, I would repair it.
There's probably a lot more rust hidden than you would like to find. Luckily that's an easy spot to fix, but unfortunately I can see you digging more and more and before you know it your car is in 100 pieces. Good luck and keep us posted.
That is what I found with most of the small rust areas of my own car - got to get in there and get it all
