Windoor Adding Weep Holes

So I noticed since picking up the ARE CX Classic. I know there are two sets of double rectangle weeps in the exterior section of the frame.

My problem is water is getting inside the interior window framing U/L sections and when the windoor is opened a large majority of that water ends up dumping into the bed. Not a pants shaker world ending issue, but was considering drilling a few small holes in the frame to allow the water to drain into the exterior catch that has the existing factor weeps.

 

Did you do this? Just got an ARE MX with Windoors

 

Hey man, I didn't end up drilling anything.
Instead, I cleaned up the seals/gaskets and added rejuvenator, then took a small/long nylon bristle style wire brush and cleaned out the existing drainage slits. That seemed to alleviate the majority of the pooling and internal leaking as far as I've been able to track since doing the above in May/June.

 

I have the same problem. Stupid question, but what is rejuvenator?
