I was thinking of degreasing sticker & surface then whacking some araldite clear on them and sticky taping over the top to keep 'em flat. Remove tape once dry..
That´s the way to go. Grab some Q-tips, soapy water and isopropyl alcohol to clean and degrease the surfaces. Then use cyanacrylate glue to stick them back, be careful with the amount of glue used, less is often more in terms of a clean job.
