Feather primer for deep scratches

just picked up a 55 chevy truck, the body is straight except for the p***enger side door wich has some pretty nasty scratches from a heavy handed grinder. is some good feather primer enough to fill or should i use some body filler?

 

filler or putty. primer shrinkage can reveal the scratches.

 

One of the catylised putties is what i would use. Unless they are real deep.

 

Dolphin Glaze is magic stuff. Expensive but worth the cost.

 

Don't know what part of the Inland Empire you are in, in Temecula we have Temecula Valley Paint Inc 951 676 2943, very helpful people. In Hemet thay have Smittys which makes me feel like I am stepping back into time.
