looks like a good product , the down side is the time involved in the whole process.
clean the paint first with polish involved , tape /mask everything , spray the product , let it cure , wetsand , polish again ..... so a min require is a paint booth and probably some basic paint skills.
if you have an 8$/h painter you may get some profit out of there... or if you can apply it with a brush or roller , that may cut on prep time
still wetsand, dust etc...
in my business , i look to simplify things not complicate them. for body shop it may be more profit cause they already have the set-up and the skills for paint.
