Water in Frame and ROPS!

My daughter-in-law brought me the new skid plate that was recalled . In the process of removing the old skid plate when I pulled the bolts out of the rear cross member about a pint or more of water came out of the bolt holes. That doesn't seem like a good thing to have water trapped in the frame like that. looking at the cross member from underneath there is a small hole in the center about halfway up the side of the tubing. Should I try to plug this hole and any more that might be in it or drill a couple of drain holes through the skid plate and frame for the water to drain out? The funny part is I haven't been in water much at all.

My wife reminded me that we did go through a semi deep waterhole on a ride a couple of weeks ago .That's where the water must have gotten in. The side main frames were fine and no water in the front cross brace just the rear. Thinking of plugging the weep holes or drilling a couple of drains. Ill have to drop the plate and take another look at how many holes are in that cross member. Didn't think to much of the skid plate. I wasn't going to replace it but she went through the trouble of getting one and delivering it so I decided to put it on. Exactly like the old one only a couple of big holes cut in it. You would think they could have made it out of a little heavier material at least. I wanted to keep the original plate but she had to take the old one back with her. Oh well makes it easier to wash the crap out from the top of the plate.
