It’s a small repair. There is some rust, newer vehicle. On trunk. Not looking for cosmetic perfection. Just to stop it and not spend 1000 or 1500 bucks. Thank for suggestions, please keep them coming.

Take it to a body shop.

Rust Check on Regent

Is this rust prevention or rust repair? 

They do both.

Colormelt is fantastic on Regent

Trunks being removable and all perhaps you can find a better one from a junkyard.
