First of all thanks to @mable to introduce me to this silicone (which also has better pictures), second sorry for my awful pictures and application I did not used silicone from ages.
Let’s start from the beginning:
I used to use the Motorsil D while living in Italy, it was a quite good silicone and quite unresponsive also easy to apply, moved in London I had to start use pads cause impossible to find that silicone here.
From pads I always felt that I had quite an harsh response even while playing, feeding string around the bearing was basically impossible without cause an accidental bind and also playing against the yoyo spin in breakway cause accidental bind, when doing that type of trick I really had to pay attention and break a bit the flow of the combo.
I started to use pads very worn out to avoid the accidental bind (never change string cause I like fat string and must use them), I tried the Permatex red but was awful, very crumbly and impossible to do a correct application, very very “solid” from the beginning and the response is similar to pads, I never tried the transparent Permatex but I get discourage from trying that.
Mable told me to try the Permatex grey in the title, 2 days ago is arrived and poorly apply it on a yoyo just to try it, not my best job for sure but I was long time without siliconing, will be better next time.
Let it dry 24 hours and then put the string and the bearing back and start to throw.
This was the result of fresh silicone:
I know that silicone (and also a bad application) need couple of throw to settle, this is after more or less half an hour throwing:
I have to say that even if not completely settled (using the yoyo more all the little bumps will go away), the response is amazing, unresponsive in a very nice way and the binds are not snappy but secure, even if my application is horrible the yoyo has a new life, much more unresponsive than before (so I cannot imagine when the silicone will be even a bit more worn out will be even greater), I put it under stress with all my “annoying” combo and lot of string layers and I went through them smooth as butter, I think I finally found my response system, next time I would like to try recessing it to see if I get it even more unresponsive, so I will try with the pads a bit consumed and a new one with recess, curious to experiment.
Everyone that is confident with his bind can use this silicone without problems, if you like a very unresponsive yoyo this is for sure one of the ways, the whole playing experience became smoother and “softer” and the response side, very enjoying this solution.
I will experiment more in the future with this silicone and trying to apply a recess and will write it, for sure this seems a perfect solution for my problem and my type of play and allow me to use my fat strings without issues.
