Hello i have a Columbia 22. I was wondering how i would go about replacing my cabin plexiglass windows. They are all fogged over, and have alot of cracks in the glass as well. Is this process hard to do? Can i install new plexiglass from Lowes? Can i use gasket maker to re-seal the windows? (i have 4 windows) Is this at all possibilty? please help me here, any responce to my post are helping to me. thanks in advance rp
