Any tips on removing/reducing these ?
Its a nasty gouge.
One day was driving to work in a downpour, and the passenger side wiper started acting funky, but it still worked.
I could tell it was about to come off, but I was on the freeway and didn't have much of an option but to keep on going and hope it held out.

It did, and when I pulled into a gas station, I pulled it off, it was hanging by a thread, and the mechanism that holds it on was in shambles.
I have no idea what was going through my head, if anything, but I got back in the truck and my hand followed some command to turn the wipers on in this condition.

Produced a nasty scraping sound, and it only went once before I turned it back off ,,, That was 6 years ago, and that damn scrape is still there.
Never really got to me, but my oldest daughter is starting to drive, and its real annoying sitting in the passenger seat.

This one flea market I used to go to, there was this guy sitting there every weekend, with a big sign "Windshields repaired for free!!".
I guess his game was to fix the most minor of chips, any anything else guide you to the shop that his brother owns.
Anyways one day I asked him about it, and as far as I recall, he said something about buffing it out with toothpaste, then some lime juice or something.
Anyone ever heard of anything like that ?

Scratch isn't visible in sig pic, its right where the sun is reflecting.

 

The toothpaste trick used to work with the old school toothpaste they used to sell years ago. DO NOT TRY IT WITH THE STUFF THEY SELL NOW. you will scratch the crap out of your windshield. Find a quality glass shop and let them buff out the scratch. You may or may not have the finesse it takes to buff it out but why take the chance and have to pay for a new windshield. Let them do it and if it is worse then it is on them.

 

I like your motto.

 

How deep?

If it is really deep, you might have to have the glass etched with acid. Most glass shops can do this. It is not something you should attempt on your own. Last time I looked into it, they were using Hydroflouric acid. Not something you want to breathe in. In fact a mere whiff of the fumes is enough to kill you.

On a happier note, most parts stores have chip repair kit. Maybe you can use the chemical in that to fill the scrape in.

 

Tooth paste and cd's work great.

 

I have the same problem with my windshield

 

There is a product that my buddy who owns a body shop uses on minor-ish scratches with a power buffer. It is called Finesse-It by 3M. You can't use any more pressure than the weight of the buffer or your windshield wil be ruined. I still don't reccomend trying this on your own though due to the major risk of more serious damage made possible by inexperience in doing something like this.

 

If it's that deep, even if you manage to buff it out to where it is not visible from the outside, you will likely have a distorted view from the inside. Like a wavy line in a funhouse mirror.

 

funhouse mirrors are cool, imagine your whole windscreen being like that

 

Tequila can do that.
