paint remover from terracotta water fountain statue

[Dilbert Firestorm]

my parents have a terracotta water fountain statue of an 18thC young boy
& girl. it is about 3 feet high and about 3-4 feet in diameter.
it was originally painted dark green shade to make it look weathered and
old. I believe that how it was when they bought it. they decided 2
years ago to touch it up with a different green color and hired a guy to
paint it. however, he used a wrong type of green (bright loud green) (I
think he didn't do it right) and my mom didn't like it.

I was told that a paint stripper would do the job of removing the old
paint to terracotta. spray the stripper at the statue, let it set and
use jet spray to remove it completely.

would any paint stripper from Home Depot or Lowes do the trick? or do I
need to get something better what the chains offer at least in the new
orleans area if possible?

my parents picked up 2 different types of paint remover (liquid & paste)
with varying results. the first liquid application via bottle spraying
got some of the dark & light green paint off. 2nd paste application got
most of the first layer of paint (bright loud green) off. did this one
week apart.

suggestions anyone?
