Wing mirror glass removal

Not going to put up a picture as I didn't take one but it's easy once you know how. I wanted to take the plastic back off my mirrors for painting this is done by putting a chisel or similar under the bottom of the mirror and popping it out towards you then pull the mirror down as it has two upward fitting hooks at the top. If you prize the top or sides first you will break these clips as I found out but if you do bottom first it's easy. Then unscrew the electric adjusting centre panel land unscrew the back cover.
