Hi Everyone, I have some fine scratches on my Seeburg V200 dome glass. What procedure and products most effective. Thanks---Preston Prue , Syracuse NY..

All kidding aside--you might try one of the automotive glass places ?

My first Continental had a large abrasion on the dome. It looked like it had been dragged across a concrete floor.

The only thing I had on-hand was Novus plastic polish. I used that with a rough piece of paper and later paper towels. It took about 20 minutes of repeated application and rubbing, but the abrasion was completely removed.
Other types of liquid polish might work as well.

For accent coloring I use Roscolene or Roscolux (for higher intensity lighting). I have a lot left over from my theater work.

Hi Rob,
Do you remember--Novus 1, 2, or 3 ? I would think 3 would do it, however, I would be afraid it would no longer be optically correct--especially on a dome ? Ron Rich

Ron, it was #2 - I still have the large bottle. There were no optical problems.

I did forget one point, I started out with fine steel wool moistened with the Novus. That go rid of the rough surface. After that it was just tedious polishing and re-application. I don't think the scratches mentioned here are bad enough to need the steel wool step.

It was my understanding that toothpaste would remove light scatches from glass and plastic.

Hi Alan,
Must have "strong toothpaste" over there !!

Hi Everyone, Thank you for all the recommendations, ---Preston--Syracuse NY.

Hi Preston,
Let us know if anything works !
Ron Rich

Hi Rich, I want to tell you, I did try toothpaste before, with negative results. I might try a glass company, because I don't want to damage the Dome. I also like Rob's suggestion, I'll let you know, thanks for the help. By the way I will be receiving my speakers back for my HF100R, that were reconed. I'm told they will sound better than the originals. My tech guy sent them to someone in Utah. Preston Syracuse NY..

Hi everyone, don't know if you can get this stuff in the US. But solvol autosol metal polish works on fine scratches if you have the time and a strong finger.

I had this problem on a Continental 2 dome. It had a big wide 1/4" about 8 inches long scratch (almost white in color). Not deep enough for your fingernail to catch on. (If you can feel it with your fingernail actually catch in a groove , it might be too deep to get out).
Here is what I did and it worked like a charm. I bought some "cerium oxide" off of E-bay from a gentleman in Michigan. It was about $15.00 and it is the best grade available. It is a very fine polishing compound used for glass. Next I got a variable speed 90 degree polisher from harbor freight. It was only about $25.00 Next I got some 3M lambs wool polishing pads.
Ok, I put the dome on the ground on a piece of cardboard (do this outside, because the slurry flies everywhere.) Also wear coveralls or old clothes.
Next you want to mix up a slurry of the cerium oxide with some mineral free water. (Distilled water). You put a dab or clump of slurry onto the middle of the 3M pad and kind of smear it around. Do this with the polisher upside down so it doesn't run off.
Flip the polisher over and smear it back and forth on the area with the scratch, do this with the polisher turned off. Then slowly start the polisher with it on LOW and keep the pressure very light. Also you don't want the slurry to dry out. Keep it wet by adding more. Also, stop every minute or so, (You don't want to heat up the glass, or it will crack.) You start to get a "FEEL" of how much pressure to apply and when the slurry starts to dry out.
The slurry should have a good portion of cerium oxide in it (not too watery ) I think I used an old glass jar to mix it in.
I didn't even use half the bag of cerium oxide and it removed the scratch.
BE PATIENT, ....it takes awhile to slowly polish it out.
KEEP IT WET....don't let it dry out.
GO SLOW and KEEP THE PRESSURE light enough that you feel the slurry working.
KEEP THE POLISHER ON LOW.. don't be tempted to speed up the polisher or the process.
DON'T HEAT THE GLASS UP... take a break, every minute or so.
Keep the polisher moving, don't stay in one spot.
It took me a few hours, letting the glass cool down, and maybe a pad change or 2.
You can't even see where the scratch was and it looks 1000% better.
Hope this helps..

I've had quite a few minor scratches I removed with Novus. You clean first with windex or #1, then use #2, clean all residue off with #1, use #2 and finally clean again with #1. It works great.
I had one Rockola 1454 that looked like someone had gone over the front of the glass with a belt sander. I had no clue to what had happened. Couldn't even see through an area about a foot high by a couple feet wide. The Novus would have taken me months so I too used cerium oxide (powder) made into a slurry. Polished it out with a slow polisher. Took a couple hours taking my time not to heat up the glass. Worked like a charm.
