i have some minor windscreen scratches on my front window from the wiper blades, like some previous owner had them on without blades or something. will this pass a roadworthy or not??
I thought a couple of hundred dollars was a very low cost particularly from a safety aspect. Messing about trying to get stuff that probably won't fix your scratches, then spending hours and hours hoping they will go.....Not worth messing about for a couple of hundred. When you have had the screen replaced.....NEW WIPER BLADES PLEASE.
Windscreens have limited shelf life regardless. After a number of years they breakdown and become hard to see through with sun glare. The other issue is they get sandblasted after a number of years. The etching acid you mentioned requires a mechanical buff to make it work. If you have the buff you might get the scratches out but if they are fairly bad you could be throwing money at a problem that the acid won't be affective anyway. Like I said only place I could buy it from was online. Buying the chemical from a Jeweller is like going to a bakery and asking them if you could buy some flour. They may or may not sell it too you, chances are they will say no. But like buying flour from a baker out of 150 bakeries you might find one willing to part with some materials.
Novus repairs windscreen scratches, chips and cracks as well as replacing windscreens. GT Glass does the same and they have mobile techs just like Novus. Both the above have operators in Cains Give either or both a call and have a chat... often it may be better to polish than replace, especially if the windscreen is rare, expensive or unavailable.
I was talking to somebody a couple of weeks ago (maybe longer) & he said he replaced his windscreen (vy) for $150.00 (l thought it would have been dearer). I think he mentioned Windscreen o'briens. Maybe wrong on that?
gave novus a call yesterday and it was $350 i got a polishing kit on its way for $60 i can pick one up for $150 online but not installed
If the scratches are bad enough, polishing may leave low spots on the screen that can cause vision and wiping problems.
From my research on the product you use, if the scratches are deep enough to leave low spots the marks won't come out anyway.
