What material can not be sprayed on the glass?
If you want to spray characters on the glass, it is impossible to follow the glass unless it is frosted. If you really want to spray words on the glass, you can go directly to the print shop, do the word, and then stick it up.
1.. First spray the glass and then stick it on the outside with a transparent adhesive tape..2. uses the special printing ink for the glass product, 3. uses the glass glue to adjust the soluble pigment and the dye toner. 4. go to the print shop and do the writing, then glue it on. I hope my answer will be of some help to you
