ProtectaClear 4 Oz. Clear, Protective Coating for Metal

Very weak coat. I got it to coat bijouterie since it oxidises very quickly on my skin causing allergy. Few pieces covered in at least 2 layers oxidised by the end of the day. I don’t know how many coats I would need to do to avoid this but I don’t have that much time.Also, it’s not very clear immediately that the solution will drip and leave a lot of drops on the piece unless you remove it constantly until drying.Another solution that dripped on the surface is impossible to remove, this one can be just scratched with the nail.Do not recommend.
