Understand my explaination :)


So, I remove the O-ring of Speedmaker

Then, I pour the silicone in the Groove, I level it (In the Groove) like so. ↓


I leave it and dry completely 24 Hours, then play it.

After a Week or two, The Silicone shape like these.


It is now curved/slant, it is pretty/slightly under the groove.

Is it normal?


Yes, silicone will not last forever. It is perfectly normal.


Should be fine.


Thanks both of you!
