Fixing scratches on depthfinder screens

[get-the-net]

Wondering if anyone has any experience fixing scratches on LCR/LCD gps and depth finder screens? I tried using a buffing wheel, but managed to make it worse. Good thing I practiced that on an old screen first. I used toothpaste as a polishing compound and had some success. Any ideas?

Thanks.

I have rubbed scratches out of the windshields of airplanes with a product called mirror glaze. If you can't find it at a fleet store try your local airport. You can do a google search also. It takes a lot of elbow grease. Use a soft cloth, not your power buffer.

Clear finger nail polish.

Will the mirror glaze hurt the plastic? I'm just worried that I'll make it worse. I think it got hit by bug spray once, so there are little pock-marks in it. Crappiebait, do you just brush the finger nail polish on, or do you daub it on? There is only one small scratch so I'd like to try the finger nail polish trick on that spot.

Should go on just fine with a "Q-tip".Just brush/daub on and wipe away the left overs.You should end up with a fairly smooth finish.Hope this helps.

Do a search on google for mirror glaze. It is made for plexiglass and polycarbonates.

Meguires plastic polish does the trick.

Where could I find some of it?

I think Fleet Farm and Target carry it. It's in the automotive section, with the car wax. Just make sure it's plastic polish that you get. Not very abrassive.

Thanks for the help. I gave it a try and it worked like a charm.

Good, I'm glad it worked for you. I've only had to do it once or twice to my screens, and since then they've been like new for years.

Perchjerker,THANK YOU! I was getting ready to send my finders in for new glass. You saved me a bundle, I owe you one.

I wish I could take the credit, but Lowrance Customer Service emailed that advice to me a few years ago. In my case the screen was not scratched, but was getting "flaky" - kind of looked like it had a lot of water spots on it. They said it was damage from the sun. I polished them once or twice and they've been good for years since then.

Flaking off... That is exactly what was wrong with my screen. I thought it got hit by bug spray, but the sun damage explanation makes a lot of sense. Either way, it works. Thanks again

Just picked up my Mcguire's from Fleet today. Used just a tiny amount and boy does that stuff work great. Thanks for the tip!!
