ref: 唔知如果用狂三系咪都一樣呢？

I am also testing thicker sponge like 狂三 max, so far, it does not curve back.

"No Name" (which is a brand in Canada) - 100% pure canola oil.

I have no problem of that.

You should put the glue first for some rubbers.

We may need to control amount of oils based on thickness, softness, and country of origin / brand that affect the degree of 曲線. Good luck.

That could be a very good business idea!

I have both rubbers on the racket, personally I find using 菜籽油 is better than BB oil, but may be little heavier.

One of the rubbers is  舊普 狂 Neo max (with glue)
