The International STa"M Forum

This new stuff called "Spray Klaf."  The claim was that it was Mei Klaf in spray form.  I have been using Mei Klaf(usually with an Eida Chareidit Hekhsher) for years.  I have never seen Mei Klaf do this.  The letters litterally are not davuk to the klaf.  I can erase them with a rubber eraser, and break them by running my fingernail over them.  Here is a picture of a Mezzuzah that I wrote with "Spray Klaf" treated Klaf.  The damage done occurred from simply rolling the Mezzuzah.

This is a very low quality Mezuzah, (I have to check several similar to these) if you see the י of והיה it looks almost like the letter J on an angle. It does not have a Rosh and instead a hook for a body. I assume it is shinui Tzura, I would appreciate your opinion on this.
