Have been given the above without any glue as used I have tried double sided tape to attach to the rib after cleaning both but did not stay on for long three days, what can I use or can I get a replacement glue strip like the one that came with it
There was a place on eBay selling the adhesive strips for these a while ago. If you look on eBay at item 331260190255 it is a kit for removing and replacing these sights.£2.49 and free postage.
Isopropanol is good, its not as aggressive as acetoneWhatever tape you use you will need to wipe the rib to degrease it before anything will stick. I use meths, it works well.
