Sand blasting / grinding will remove surface rust but it won't remove rust from deep in the pitting.
Any bare metal around the repair must have a corrosion resistant material applied to protect against future corrosion.
Note: Most corrosion removing I neutralizing chemicals have safety / health concerns. Always follow manufacturer's recommendations when using
corrosion removal equipment and chemicals.
Corrosion Perforation
Corrosion Preforation
Overview:
Corrosion perforation is any hole that has formed because of a corrosion condition When repairing corrosion perforation you must remove all corrosion
prior to beginning the repair.
A cosmetic body panel does not require replacement in all cases of perforation. A new partial panel can be hand crafted or cut from an OE panel to
accomplish a good lasting repair
Corrosion perforation can be repaired using a repair panel and the overlap process or the backer panel process. The type of section to be used is usually
determined by the location of the condition. A lower quarter panel can usually be repaired using the overlap procedure. On the other hand, using a backer
panel to repair corrosion on the roof would be a better choice. Areas like a roof, which require a smoother transition of the new replacement panel and
the existing panel, the backer process usually works better.
Roof Panel Repair
Roof Panel Repair
Overview:
When evaluating a corrosion condition on a roof panel you need to take into consideration things like extent of the condition. Will you need to remove
the windshield to do the repair? Can a repair be made without removing the headliner? What type of joint would be best suited for this particular repair?
Roof Panel Repair using a Backer Panel:
1. Remove all parts necessary to access the damaged area.
2. Remove all the corrosion from the panel being repaired. If there is any corrosion left behind, even if it's deep in the pitted areas the corrosion will
return.
