Duramax, please research epoxy primer more before you do anything else.
Here's a random google search result about epoxy primer prep "example" of a TDS...

Where in the attached does it say anything about prep for rust
pits?
Specifically it says "Surface must be clean, dry, and in sound condition. Remove all oil,
dust, grease, dirt,
loose rust, and other foreign material to ensure
adequate adhesion."
This is a standard SSPC coating application specification used in the industry.
SSPC standards are:

You are not going to find a SSPC-SP5 as a prep for epoxy primer.
Ask anyone NACE certified if you should be blasting, and they will tell you "no".
Sand blast if you don't believe me.
