Can a newbie control rust? or Honey I Think I Finally Found THE Car!

POR-15 is a Moisture cured Urethane encapsulant (thanks Bodyperson! ) that stops rust cold

As a newbie, I appreciate name dropping! What would a situation look like where a person would not want to apply this to surface rust?

with some rust resolver gel, a wire brush, some new seam sealer and patience, it could look like this!

Is seam sealer a different product than the POR-15?

:thankyou:
