What is the best SILICONE lubricant to put on my rubik's cube?

I recently put on some 3 in 1 Lubricant (it also says that it waterproofs and protects), and it felt really bad for the first day or so. Then, I wiped all the pieces off and blow-dried them and it's better than ever, but I still think it could be smoother. Is this the best lube or are there any other good ones?
