@boretennis

I have attached the pic if that can provide any insight.

Yes I am also thinking about getting the sand paper and trying to remove it.

Even then I would have assumed that rubber would have some glue when I applied 2 layers of Glue (Revolution Nr.3, Glue 50ml Normal Viscosity).

As you suggested it may be due to lacquer, I will try to sand it a bit and try to glue it again. Sanding might remove the lacquer a bit right?
just sand it once to create some pores, don't sand off the lacquer
swipe once through out the edges and swipe once in the center of the blade.

@Tyce @NetProphet , After playing with the blade the black started coming off so eventually I ended up removing the rubber. But I am unable to remove the glue from the rubber or let me say the other way around, I dont find much of glue in the rubber at the first place. It seems like everything is soaked.

I am sure that I did apply 2 layers on it. Am I missing something?
Hey Coolchap
It could be that the glue is very thin, probably a thin viscosity glue but I've never used Rev 3 so can't be sure.
But even with thin glue there is usually a few pieces around the edge of the rubber where you can pinch it and then peel it off.
If this is not the case, and the sponge looks smooth then you can leave the glue on it and just apply layers over it.

I would also (probably with 800 grit or thereabouts) give a light sand to the blade to allow more adhesion on the lacquer.
Don't sand hard, just lightly pass over the lacquer, twice left to right and twice up down will be enough. You don't want to remove the lacquer, just roughing the surface of it so the glue will stick better.
Then go again with 2 layers on the sponge and one on the blade.

Make sure to roll the brubber firmly when applying to the blade.
Again, not too much pressure but just firm enough remove all air and ensure the glue is pressed firmly everywhere to the blade.
Take your time lining up the rubber to make sure it's straight.
Start by lining up the straight edge at the top of the handle, press it on there first and then roll towards the top.
This post is very 'wordy' and I'm probably over explaining a little but I remember messing it up a few times when I first started gluing rubbers so I hope you can nail it this time!
Good luck 😎

Learning:-

1. Sanding a blade will help
2. Apply 2 layers of glue on rubber and 2 on Blade if it is Rev 3 Normal viscosity.

Might have to do redo the red one too. It slowly coming off little by little but not doing right away.
