but what acid would be unable to eat through a water balloon, but still strong enough to eat through automotive paint?
Paint strippers often come in plastic bottles, but destroys the bond between paint and metal.
Also even light acids like vinegar can be enough to etch and damage, but not remove paints - or in the case of the cybertruck, accelerate corrosion on the stainless.
Those plastic bottles that hold diluted acids and alcohols are usually PP (polypropylene) or HDPE (high density polyethylene) or similar plastics that are a lot tougher than thin, flexible plastic bags (LDPE, PET) and I imagine balloons too
