I think an exterior paint will be fine for an unheated garage and it will be
more water resistant since he's washing cars in there to the point of mud
spatters on the upper drywall. I wouldnt however use just any exteror on
the cinderblock (so I am assuming the cement blocks are) as it would require
possibly as many as 4 coats to deal with the porous nature.

Retape and spackle as needed. Spot prime repairs and prime block. My
preference is an acrylic primer like BM Fresh Start. Top coat with
paint of choice. My preference is BM Super Hide in bone white. It's a
second line interior paint, more than good enough for a garage, covers
well and is priced right in 5 gallon pails.
FWIW
YMMV

Just use the exterior paint one coat or 2 to cover, but mud pealing
sounds like moisture is afecting it

anti mold material.

i couldnt tell the difference between interior and exterior and some
paint is marked for both

Since a garage might be in a somewhat grey area between being
"interior" and "exterior", may I suggest that you Google something
like "using exterior paint inside" and read all the various reasons
that a multitude of sources say it shouldn''t be done.

For each reason not to do it, see if that reason fits your
circumstance and decide for yourself. It appears to me that you could
make an argument either way when dealing with an unheated garage.
