siliconing yoyo

The silicone pads in my legacy and speeder 2 have popped out and i want to silicone them.
Are the response grooves of them too shallow to be silicone and will the silicone fall off easily?

Go silicone them. They are more than deep enough. Almost all current model YYJ’s are safe to silicone, including some that don’t come with the YYJ silicone response pads, such as the Lyn Fury that uses rubber gasket o-rings.
