I'm planning to buy this side skirt

I couldn't find lots of posts/threads of people installing this. I assume that it's similar to CS style side skirt which we will have to drill into the rocker panels.
Does this sideskirt has pre-drilled hole? How many holes do I need to drill? Can I just use POR-15 for rust prevention?
Thanks
