I bought some of that glass etching spray at the weekend and gave it a go.
I folloewed the instructions as best I could.It said apply in thin layers but didnt say how many!
I gav it a couple of coats abut when I cleaned up the end result the frosted section rubbed off!
I thought it was supposed to actually burn/etch into the glass not just give a frosted effect.

Am i doing anything wrong?
