Daily drive, if you read the back of the can on POR-15, it does say it will seal in the rust, but what you said is wrong, rust forms from a reaction with oxygen, POR-15 seals in rust thus sealing out Oxygen, therefor the rust is still there but without Oxygen for the metal to react with the rust cannot advance any further, the only reason they even have you remove the rust is so you get better adhesion. POR-15 will be your best bet with rust prevention.
