Acrylic scratch removal.

Is there any PROVEN (concrete, solid) method to remove scratches from my acrylic tanks? The scratches are killing me. I contacted my local glass body work shops and they informed me that there is no way to get rid of them but the person I purchased the tank from told me that he had taken the tank to a body shop and had them buff the scratches out. Someone is lying to me and I would like to have it cleared up. Thanks in advance. 

Awesome. Thank you very much this info has helped me out a lot

Mark, I actually have this kit and a friend tried wet sanding it on an empty 75 gallon tank I gave him and he told me that after a few hours of scrubbing he gave up lol granted he was not using a magnet but now im curious to try this on my tank. The grits range from 1500 to 12000. Do you think if I try hard enough with the 1500 I will get somewhere?  

Yes, bad scratches take a long, long time to remove, especially if it's filled with reef animals.

If the tank is not currently in use, it's better to let ReefOn have it or scrap it.
I'm embarrassed that I forgot to ask what size this tank is? If it's anything less than 100 gallons I'd scrap it and buy a used glass tank.
In my opinion it's just not worth more than $100 to have this work done. There is a glass 120 gal tank for sale here on the MB for $150. It's drilled with overflows so that's a bonus.
This is just my opinion

Another factual consideration is the tank's age. From all the tanks I've seen, an acrylic tank older than 7 years is not worth repairing. The plastic reaches a certain age where it becomes too brittle and nothing can fix it. There is a condition called Crazing. Crazing is thin, almost invisible, spider web like, jagged shatter lines occurring mostly near weld joints(corners). It is a serious indication of old age and weakening. It occurs because some of the chemicals used to create and hold the polymer/acrylic molecules together in the first place are slowly but continually evaporating. Water on the inside slows the chemical's evaporation on the inside. This means that leaving an acrylic tank to sit dry actually accelerates crazing and weakening because the evaporation is occurring on both sides of the panels.

Acrylic can be formed into cool shaped aquariums so it's interesting that way. The only other advantage I know of is that it is lighter weight than glass, but that advantage only lasts for the time it takes to lift it into place.

Again, my 2 cents worth

Here is the tank Mark is talking about:

That's it. Bob, you're awesome.
Isn't this group fantastic. So many friends, Wade included.
Years ago, Wade bought a tank and I helped him move it. It had a Flatworm epidemic. He and I dipped every rock, every coral, everything in a tub of freshwater before placing it back in the tank in it's new home at his house. Some of the best 8 hours I ever spent.
