Has anyone ever tried this and had any success with it? I have a really nice picture that got scratched in my move to Washington. It's a fairly bad scratch, but only noticeable in some lighting situations. I saw products on the internet for applications such as motorcycle windshields, which I am considering trying. I just don't want to make the situation worse than it already is. Thanks for any help.

not sure about plexiglass, but toothpaste (or jeweler's compound) is great for buffing scratches out of sapphire watch faces

those motorcycle windshield kits are essentially small detailing kits, with a rubbing compound and a swirlmark remover both that are very fine and suited to plexi glass, dont take autopaint rubbing compound to it, they work ok on getting out scuffs or very very fine scratches, it will take a lot of elbow grease none the less.If you had a dual action buffer it would help a ton, with a brand new pad of course. it sounds like it might be a bit deeper than is possible with the motorcycle windshield kits. and then you are stuck with the scratch or the price of a new piece.

cool puzzle though, and good luck

i would try to get a small piece of plexiglass, scratch the shit out of it. then try to fix it using different techniques you hear about. I wouldn't try anything on the final thing without absolutely knowing it's going to work.

I've never heard this before but i was just thinking about it, maybe clear nail polish?

and why is there a horribally unproportional planet (or a planet period for that matter) in the ny skyline?

You can't EVER completely get rid of scratches in acrylic/plexiglass.

You can get polishing compound down to like 4000 grit that will make it almost clear again. But in direct light you can still see a bit of frostiness.

If you just dont want to get a new sheet of acrylic (you can get one that size for ~35 bucks from lowe's), get some 600 grit sand paper, 1200 grit, 2000 grit compound and 4000 compound and be prepared to spend a good couple of hours. (all that is going to cost you, you guessed it, ~35 bucks).

Holy fuck, how long did that puzzle take you to put together?

That is great advice on trying the techniques on a smaller specimen. I will definitely do that.

As for the puzzle, I bought it back in 2000 when I first moved to Raleigh (before 9-11). I thought it would be really cool to have a 12000 piece puzzle, but at the time I didn't even realize it was New York City. Anyways, the 9-11 attacks happened and I realized that I had a pretty neat thing, so I decided to put it together. I would say total actual working time, it took me about 3 months, but I stopped after a month or so cause I got bored and didn't start for another year or so.

And yes, the fact that Saturn is in the skyline is gay.

^seriously it's not worth the time or money. those polishing compounds + pads + sand paper add up quick, and thin acrylic like that is REALLY cheap.

I would call up a local glass shop and ask how much a new one would cost. Plexiglass is really pretty cheap. We used to get 10' x 20' sheets at work, and they weren't more much more than $100, but we did get a wholesale industrial rate. If you want it to be a little more durable, I would get a sheet of Polycarbonate, but that would cost a lot more. Could also go with glass, but it would be a lot heavier.
