Thanks to this thread it gives me more info and technique require for me to proceed with the re-skinning of my M9

Thanks to bro @ricleo for sharing the re-skinning info help me a lot
I notice Aki-Asahi M8/M9 leather skin has a cut out at the frameline lever so this prompt me from not using or buying the clamp wrench and also uses the wet technique but I've used water instead of the non-moisturizer antiseptic gel aka gel hand wash. Here are some pix not complete but just some tidbits
I'll skip to the removing of skin those are easy the easiest actually.
Here's the M9 naked ^_^ (maybe asked why there's an alcohol? I use it to wash and clean my hands hahaha)
Now cleaning up the adhesive residue.. My technique is what my father told me before when I was young. To remove adhesive residue you need an adhesive also e.g. scotch tape. this is what I always do when I am removing price tag sticker on the items I bought after removing the price tag sticker still have some adhesive left over I either use the same sticker or use scotch tape around 95% of the time this works.
Using scotch Tape to clean off remaining adhesive (don't want to use alcohol or chemical as this is something corrosive to the plastic/paint etc)
Here's the before
With Scotch Tape to clean the adhesive
After Cleaning using the scotch tape
The Skin sticking time! Started working on the Frameline Lever using the wet technique. I've damp the leather sticky side with a little bit of water
