Can I remove old etched reg number on glass?

Post by MrNorm »

The side glass in my car has got the registration number etched or sandblasted in place from a previous owner. Once I am back on the road I am going to get a new Reg # since the existing one is not the correct year, so I'd rather not have the old number on the glass. Is there anything I can do to erase it or at least make it less noticable?

One possible option is to start polishing! If I were able to get rid of the opaque texture of the letters it would be less noticable. If I could make then transparent like the rest of the glass it would be an improvement. Alternatively could I polish the whole letter area, even if I ended up with a rectangular 'dimple'
If that is not feasible I could blast or etch the whole rectangle. Is that easy to do? I've got blasting equipment. That would leave an opaque rectangle but I think that would be better than what is currently there. However, I wouldn't want to further blast/etch the numbers that are already there, not sure how to avoid that?

Obviously whatever I do I don't want to risk any damage to the glass at all....

Suggestions would be appreciated :thumbright:

Jewller's rouge is the stuff to polish out small scratches.. Don't know if it would be fierce enough for that though!

May have to start with wet n dry... slowly getting finer and finer. Good luck Gav!

You can take the etched letters off using an air polisher (mop) and some coarse cutting compound. I use R-M Bril, but 3M or Farecla will do the trick, I took some massive scratches out of the Road Runner's glass without distorting it.

I think I've seen windows with rectangular areas that have been blasted, or re-etched to obscure the old reg no. Not pretty, but it would get rid of the old no. :(

I'm sure the traders know a trick or two ;)

Thanks for the input so far guys. I do have some jewellers rouge which I purchased to polish up the windows, hadn't thought about whther that might be usable to take out the reg #s, might try that though agree it might be a bit of a tall order

Ivor, that sounds like a workable plan, though one of the few tools I haven't got is an air (or electric) polisher - at least not the type I think you mean (the type you would buff out new paint with, right?). Do you think an electric car polisher (light duty, that you'd apply wax with), a D/A sander or a drill attachment would achieve the same end? As far as the cutting compound, is there a particular grade or something I should use? Would I need a different grade for the 'de-etching' and the rest of the window, or just more time?
I do have some scratches elsewhere on the windows so maybe could kill two birds with one stone? I thought conventional wisdom was that anything deep enough to be felt with a fingernail was deep enough to leave distortion if you polished it out? Not to mention reducing the thickness of your glass?
If you did not have that problem this sounds a promising method.

Re-blasting I could do but again wouldn't want to further blast out the old numbers - that could be difficult to mask off for example. But would certainly consider

Mark, I hadn't heard of micro-mesh. Is that suitable for glass as well as acrylic? Presumably it wouldn't be practical to use that to polish the rest of the window as well, I assume it is a manual process (manual = good control :thumbright: though labour intensive :? )

Gav, you really need a pro polisher to get the scratches out and depending on the grade of compound you use, you can indeed put a dip in the glass.

I was down at Thatcham a while ago looking at the "hooky" cars that they use for police training and you could clearly see the depression where etched registration numbered had been removed heavy handidly.
