I've also adhered them with two sided tape.
There made of 16ga steel.
There sent out with no paint or primer but I can do it to suit if needed.
I've been putting colored vinyl from the sign shop down for the back ground color and they have been turning out well.
I'm charging $30.00 for one side or $50.00 for both. Some folks are only buying for the door side but some I've done including my own has two doors.
For every sale $5.00 goes back to support the T&TTT forum.
Just need the size and I need to know if you want them pre drilled for mounting.
PM me with any questions.
