You can always scrape away the silicone. Go to yoyoskills.com.
A silicone job can always be redone. But you live in the US where you don’t have to pay 20 dollar shipping for everything under 1 pound. So you can order pads without having to pay major amounts of money.
you don’t have to do a silicone job on the flow groove, it comes with flow groove pads and you can buy extras.
