Hi there. I had someone out to fix my garage doors as they weren't opening properly and we discovered that the issue is that paint melted off the door (from the summer heat) and has adhered to the plastic door protector. The repairman feels that if I can get the paint removed off the plastic I won't have the problem again. Does anyone have any suggestions? Home suggestions (ie: affordable things I might already have around the house) are particularly appreciated. Thanks!
