I have a 2000 jk on 33s with 33s and a 4inc suspension lift and my door guards are coming unglued!! Do I even need them? Ik they help with preventing damage to the door lip or w.e but does it help with keeping water out too? They r cheap to replace but if I don't need them then I don't wana spend the extra $20 for them!! I herd they r held on by 3m tape so what are you thoughts?
