Removing a poor overpaint

[bikeworkshop]

We've got a cannondale frame where the original owner decided to paint over it with hammerite to make it look "less nickable" locked daily in town.

On the positive side, it wasn't stolen.

On the negative side, it looked so horrible that he p-exed it with us for a nice looking frame

I thought I could strip the topcoat without damaging the original factory paint - my thinking being his top coat is solvent based, whereas the underlying factory finish is powder coated.

Any knowledge/probability?
I know a heatgun and scraping might be the answer but I'm very lazy.

Hammerite is horrible paint but is quite 'soft' so perhaps careful use if a heat gun and scraping might work.
