===What's the "best" way to handle body rust?===
 
The "best" way to complete a task often implies the presence of the "best" conditions.
 
 
Not just the "best" tools, "best" skills, and "best" amount of time. Also, the "best" payback on your investment of resources.
 
 
So, the overall "best" way to handle rust may not be the "best" way for you or your particular situation.
 
 
Here are some of the more significant factors that will affect your choice of how to handle rust on body panels:
 
 
*How bad is the rust?
 
*What tools do you have? Do you have access to a sandblaster and welder?
 
*How much money can you spend?
 
*How valuable is the vehicle? How rare? Resell value? Worth investing time into?
 
*What type of climate do you live in? Dry or humid? Summery or wintery? Salt in the air (near the ocean) or on the roads (snowy winter)?
 
*What's your plan for the car? Daily driver? Show vehicle? Fixing it up to sell?
 
 
That being said, the general consensus on the overall "best" way to handle body panel rust is this:
 
 
*'''Remove minor surface rust with phosphoric-acid based products. When down to bare metal, sand, clean and dry the panel, and spray it with a high-quality 2-part epoxy primer/sealer.'''
 
 
*'''If it's anything more than minor surface rust on a body panel, cut it out and replace it. In most cases, this will involve carefully butt-welding in a patch panel.'''
 
 
*'''If you're dealing with a complete vehicle body with rust, have it commercially dipped.'''
