@maw8908 – yes – the way to do this right is the replace the whole door. But for 90% of people replacing the door themselves is not easy. Sure a new slab door costs $29 but have you ever tried hauling one home in a Civic (plus you got to haul away the old one)? If you can’t install it yourself your looking at $50 to $80 to have it installed. Filling it is an easy DIY for somebody.
