RUU override custom kernel

[thorasaurus]

I searched and didn't find any specifics on this. I convinced Sprint to give me a refurbished Hero (since my trim by the USB cracked and since the usb has been finicky at best).

My question: If I RUU, will it override the custom, overclocked kernel I installed (I know it will do the ROM and apps)?

Another: if Sprint has already agreed to give me the replacement, will they care that my moisture stickers are red?

Thanks much. You guys rock!

Short answer: yes. The RUU wipes literally everything, including kernels and even the radio.

Thanks Chrome! Any idea about the moisture indicators after the fact?
