This can apply to any brand of truck.
why is it that whenever Rusty sheet metal gets cut out and a patch put in, it looks fantastic once finished and painted for a while but after a year or two rust comes thru the paint and you can tell EXACTLY where it was cut out and where the seam between parent metal and replacement is?
I notice this all the time. Pull up next to someone who has had patch panels put in over the wheel wells and it sticks out like a sore thumb.
i have a 96 Dakota and 2 summers ago I replaced the passenger side rocker panel. Now I can see thru the paint exactly where I MIG welded the new to the original. My son has a 99 Ràm 2500, same story on his truck bed especially over both wheel wells and I think that his were panel bonded in place. That truck looked awesome when he got it along with piles of receipts for panel bond , patch panels paint and such. So that would rule out heat affected zone induced by welding in the new metal. He will be looking for a new bed for that truck. I have an 85 Dodge pick up that I will be doing some body work on, this summer. It needs some repairs to the wheel wells on the bed and I will have to replace 1 rocker panel on account of being smashed in, not due to rust.
since rust free truck beds don't grow on trees I will be replacing what metal needs to be on the existing one. (This one isn't as bad as some trucks around here that at almost 30 years newer, but I do not want to go thru the work knowing that in 2 years it will look worse than it does now)
i also know that most patch panels sold on the aftermarket, are imported. Is there something like dissimilar metal composition between original American steel and these patch panels?
being as how my son's patch panels were bonded and not welded I am beginning to think that I can rule out the welding as being a cause.
I also have a plymouth volare that I have done some body work on (that one is still in progress) and I have some solid patch panels cut from other dodge aspens and plymouth volare's in the junkyard years ago. Will using patch panels cut from actual cars the same age, using the same grade sheet metal as was used on the car to begin with// vs aftermarket parts, have any effect on preventing this problem?how can it be prevented?
