I would check the bead lock stirp that it lock in good, or maybe take out the lock strip and get some soapy water spray the rubber on both side of the glass. Reinstall the bead lock strip make sure it is set in place snug and let set in the heat of the sun one day. That should seal it, unless rubber not right location or there is rust in on the pinch channel that will have to be fixed first. If the used rubber damaged in the channel or the bead lock channel it may leek. if the bed lock strip has been stretched too much it may need a new bead lock strip to seal. Tools to uses are plastic trim spades take out the bead lock strip push center alum clip to one side @ the center bottom pop out the bead lock strip work it out all the way around. Take the tool work out around the glass in side and out side to loosen the seal on the body and the glass channel. Once seal is popped start one of the corners with light pressure on the in side @ the same place your working on the out side glass channel and around till the glass pops out (( take your time go slow go around a few times if you have to till the glass starts to pop up all around )).
