I have a 1974 240D W115 that my dad bought new. The car has some smallish rust issues. I've looked on the web and there seems to be three approaches for fixing rust, but everyone is focused on the huge rusted hulks - not the smaller preventative fixes. The three most common approaches to body rust are:

1. Rust converters: Rust Bullet, Corroseal, Ospho, Rusteze, etc,
2. Encapsulators: Eastwood, POR 15, etc.
3. Grind and paint:

I have attached the level of rust and the location for the rust on my car. There are 5 locations:

a. Passangers door by window and handle
b. Passangers front wheel well
c. Passangers front door jam near floor
d. Drivers rear body by trunk and rear window
e. Drivers front wheel well

None of the rust areas are really bad which makes me think that the old school grind, prime and paint is the best method.

What is the general consensus on this board. Would you use an encapsulant or a converter and then prime and paint?

Also, how would you paint these areas? Would you spray or brush and where would you get the paint? I am OK with spray can painting and I don't own a sprayer.

Thanks for your help.

Dave
