Hi spike
couldn't help smiling to my self after reading your blog about the glass panel firstly "PUT THE SCALPEL AWAY!!! their is a far simpler and kinder way to strip off the old glue residue. if you follow the instructions you can recover from your night mare!
OK Firstly you need to lay hold of some white spirit only white spirit i cant guarantee anything else will not strip of the paintwork! you will also need evostick contact adhesive 731 will do but it must be contact will also need to get a modelers tin of gloss black paint and a fine brush and plenty of kitchen roll (oh and while you are at it a cup of coffee LOL)
Secondly you need a CLEAN flat surface lay out your kitchen roll on the surface to stop spillages all over the place now pour out enough white spirit to cover the glass panel, leave it for about 1 1/2 hrs to soak into the residue glue/foam same thing with the plastic panels x 2 which will also need to be cleaned in the same way.
Thirdly you need a piece of wood e.g. a lolly pop stick sanded to a blade shape to scrape off the glue, if the glass has not been messed around with before all the residue/foam will easily peel off leaving you clean surface to bond to.
Forth part now run some moderate warm water and plenty of fairy liquid soak and wash completely with a nail brush this is to remove the oils present in white spirit.
Next when you have dried the three pieces with a hairdryer you can now touch up the paintwork you scratched off with the scalpel hold the glass up to a window the only light showing should be red and green touch up the back of the panel with black till all the scratches have been painted out allow to completely dry.
Lastly you can now carefully mask off any area not requiring adhesive by positioning the frames on the glass and taping to there edges * remember the press up locking tab goes to the bottom edge of the glass* apply adhesive to the frames "not on the edges just the flat surfaces that bond to the glass". apply thinly adhesive to the glass and allow to set with manufactures instructions remove masking and carfully bond the two frames to the glass by pushing frame hard to either end then nipping in the middle where they meet then firmly applying hand pressure all over. Once you are happy that the bond is secure you can mount the touch glass onto the PCB ensuring you remove the little 5mm locking screw which passes through the PCB to locate it in position ensure all the plastic legs support the PCB and don't be tempted to force anything
hope this is some help to you
