How do I clean GlassPrimer™ paint overspray on backpainted glass?
To clean off any paint overspray on the front of the back-painted glass or on the edges of the back painted glass, use light steel wool to remove overspray from edges of the glass and use lacquer thinner and a cloth to clean off overspray on the front of the back-painted glass. For really thick overspray, use single edge razor blades to help remove the thick overspray followed by the methods suggested above.
