Corrosion
Overview:
There are certain rule of thumb conditions when repairing any type of corrosion:
All rust / corrosion must be removed or it will return.
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.
