I bought a 71 Challenger convertible that sat for years stripped of paint and has lots of surface rust. I tried blasting the car which removed most rust but some panels are pitted and I'm sure there is still some rust in the pits.

What's the best way to handle this so rust doesn't comeback down the road. After blasting everything, I was going to spray the car with Eastwood Rust Encapsolator or Rust Bullit. Any other recommendations to insure the rust doesn't come back?
