Hi All,



It's my first thread on this group ( nice website :up )



A very frustrating thing has happened to my rear window as I see a couple of circular scratches near the middle of the window . This was probably done by a wash shammy either when drying or washing ... small rock must of scratched the surface of the glass by being trapped in the glove. :(



What can I do now as the scratches are very faint but i can feel them with finger . Can I fix it or do I really need to claim it under insurance and change window . I see the scratches when car is clean through rear view mirror.



Any help is most appreciated,



Thanks folks

John
 
you should post in "Autopia University" but try taking a razor blade and smoothing the scratches with that and they should dissapear
 
Will do ... thanks bronze2006.



Never thought a razor blade would do the trick , how is it possible ? The half moon scratch is about a hand lenght long.



Won't the razor risk scraping the glass even more ?



:(
 
ive seen it done it works great, makes the glass look new, the razor took out some large scuffs and scratches on a windshield
 
Wow ... that's hard to believe but if it works it can save me a load of $$ . But how is this possible when there is all the talk about polishing the glass etc...



Even though I can feel an ever slight groove in the glass ?



So you are saying to pass the razor perpendiculary to the scratch

Nice graphic :cool:

exactly what the guy from the body shop did, it doesnt work with cracks or deep scratches but for surface scuffs and stuff it should work
 
If you can feel them with your fingernail, they're probably too deep to polish out. Depending on cost you might want to contact a few local glass shops and ask about repairs. There are professional glass polishing kits that can remove *some* damage. Experience is critical here but if you plan to replace the glass anyway, it might be worth the risk to save some $$ and a claim against your insurance. Just my $0.02CDN.
 
If you can hang a fingernail in the scratch it will NOT polish out. Should run about $75 to polish out in an hour or less. If more time is needed add about $60.00 more to the first price.
 
I've merged these two threads for you. :xyxthumbs



For future reference, you can delete your own posts/threads if you want.
 
Folks... i've just asked my local windshield repair shop and they do take the risk of polishing the back window because of it's fragile nature( it may break ).



Is this true ?
 
~One man’s opinion / observations ~



This is for information, I have not tried, therefore cannot recommend this product;



Janvil Products, Professional Scratch Removal System (scratchpolish.com)



This system is designed to repair most of the scratches and

surface damage in glass that you will encounter. Can be used

with either a drill or a polisher with a 5/8"-11 spindle connection.





~ Hope this helps ~

Would you rather listen to the opinions of amateurs? or follow the advice of an experienced trade professional?

Like the "experienced trade professional" that offered one of our members advice about paint in this thread: http://www.autopia.org/forums/showthread.php?threadid=34059



Owning a shop, or claiming that one is a "professional" does NOT magically imbue that person with knowledge, wisdom, honesty, or authority. IMO, consumers should seek second (and third) opinions from any source they consider trustworthy and knowledgeable, "professional" label notwithstanding.

Now i'm confused :)



Still skeptical about those starter kits though ?

Is this true that the rear window can break with the pressure of a polisher



Thanks again ,

Johnny
 
It is not the PRESSURE of the polisher!! It is the heat being generated from the polishing technique. To get out scratches in glass (and we do it as a profession) We have also done the rear glasses. The polisher generates heat, and then we use water to cool it. Get it to hot and it breaks. This is a time assuming job.So it takes a 6000 RPM polisher, (NOT a drill or pc or rotary) Compound, and water to work the glass to remove it with a certain size pad (NOT a polishing, wool, or finishing pad-BUT A glass pad) to remove these scratches without causing DISTORTION. You can remove the scratches a lot quicker if DISTORTION is not a concern.



I am not familiar with the janvil polishing system. I think it sells for around $30.00. Our compound is $100.00 per pound. Our charges are $75.00 for the first hour and $60.00 each additional hour. We have never taken longer than 2 hours to remove scratches. Our time starts when we tape off the car to TRY and hold down the mess the polisher makes. Even still it has to be washed several times after.



Hope this clears up some of the glass scratch questions. It is NOT a quick or cheap fix.

Sounds like very good advice from an experienced trade professional.

:rolleyes:



<sigh> You're right, Frank, it probably is very good advice. It was also elicited by asking this pool of "amateurs". You completely missed my point: calling yourself "professional" doesn't make it so, and it doesn't lend any credence to your opinions; respect must be earned. Surely, "as a detailing professional", you agree?



And Glassman, please understand that this doesn't reflect on you at all. Take a look at http://www.autopia.org/forums/showthread.php?s=&threadid=34048 to get a better understanding of where I'm coming from.



All that said, I apologize for having 'jacked the thread. I should know better by now than to allow myself to be baited into this kind of stuff.
