If your IP was never sent wouldn't it be impossible for them to send you back the information you requested?

It's VPN's all the way down...
I'm mostly joking, but if you purchase the second VPN anonymously (gift card paid with cash, bitcoin, etc) this would do a pretty good job of ensuring your anonymity against most casual snooping. It's not going to hide you from the FBI, but it would prevent either VPN provider from tying your browsing activity back to you (unless they cooperate with each other).
I used to use a VPN to hide my browsing activity from my ISP (Comcast), but now I have an ISP that I trust more, so pretty much only use VPN on public Wifi to help protect my traffic.
