Rear Wiper Arm Removal - Glass Scratch Removal
I had a little mishap with the garage door and the only damage is a some scrapes to the rear wiper arm cover (the plastic piece) and some scratches to the glass. Very minor. Please help on the following:
1) Local dealer had the wiper arm cover in stock and per parts guy easy removal; however not for me. I removed "cover" protecting the nut, took off the nut and cannot for the life of me get the wiper arm off the post. I tried WD40, pulling, pushing, wiggling (per post on the internet) and this thing will not budge....... am I an idiot (of course, see first paragraph) that I cannot remove it? If youknow how, please school me.
2) How does one remove scratches on glass? I tried some rubbing compound and some headlight repair kit. Autopart store didn't have anything. Do I do see a professional windlow glass repiar shop?
Thank you in advance for your help.
