Shaving Drip Rails on an 85?

[flatblackclassic]

I'm a newbie to this great board and for my first question I want to know who has shaved the drip rails on their 73-87. Several people locally have cautioned against shaving the drip rails saying they will definitly leak. I fail to see where it would leak though since there is a seal on the top of the door to keep water from coming in. I'd like pics, info, whatever you guys have got. I'm confident about shaving everything else on the truck and don't want to leave the drip rails on if I don't have to. So what does everyone think about shaving the drip rails? This will be an almost daily driven truck but I dont' see it being a problem really. ANy help is greatly appreciated.
