Used Rust Encapsulator, want to repair correctly with epoxy primer.

I have a 1997 F250 that is in very good condition, except for the roof. The paint has failed and some rust has started. I have applied Eastwood Rust Encapsulator to get through the winter temps and precipitation and plan to prep and repair starting with SPI epoxy primer once the weather improves. Do I need to do anything specific in the areas with Rust Encapsulator in addition to sanding with 80 grit?

Thanks for a great forum and products! And thank you in advance for any assistance and advice you can share.

Ospho will probably work to remove all the encapsulated area, if it is an acid based product.

Do a search here for neutralizing Ospho if you are not familiar with the process. Must be done before epoxy if you use Ospho or any other phosphoric acid based product.
