RE: [GSAS-Member] Safe in Tank Acrylic Sandpaper

["Susan Welenofsky" <welenofsky@comcast.net>]

I used an electric sander. It worked great. What would be better is a
pneumatic air-driven buffer, like the kind used by auto body mechanics. No
risk of shock when wet sanding. I just made sure I had mine hooked up to a
ground fault interrupter, and got the sandpaper on the pad lightly wet. When
it got too clogged up, I rinsed the plexi and the paper. 2000 grit will make
it hazy. Packs of the McGuires 2,500 and 3,000 are $25. There might be
something else. I'm not sure what grit the "Magic Eraser" is.

I have a plastic tank with some minor scratches so I will buy a few sheets
from you.  Question:  Are the scratches deep enough to use sandpaper or can
you buff them out?  Regardless, looks like a great newsletter article!

I found McGuire's 2500 sandpaper ($20 per box, must buy whole package). I
bought 2000 wet/dry grit today (5 sheets, $8). I'm going to use the sander.
They have finer grits at a different store, in Kirkland. So, I can safely
use the black wet/dry sandpaper while the fish are in the tank? I would buy
a package of that or 3,000 if someone wants to split it with me. I can get
an auto dealer/worker discount on the stuff.

I have successfully used the black wet dry paper in a couple of my acrylic 
tanks. I have heard that the micromesh works well but have not found it 
locally in a fine grit.

Depending on the depth of the scratch I would use 400-1800 grit, the 400 for

only the really deep scratches, then follow with 600-800 and then 1200-1800.

I sand in same the direction as the scratch. For teeth marks I would sand in

a circular motion and probably use 1200 first.

You might want to start with the fine 1200-1800 first to see the effect, but

the finer paper requires more effort to see the results. Be sure to always 
progress from the course paper to fine. Sand as little as possible to 
prevent the area from looking distorted.

After using the fine 1200-1800 grit paper the arcrylic can be polished with 
a cloth and some of the arcylic polishing compound available at the stores. 
I think similar results could achieved using other polishing substances, 
like baking soda. If you didnt use too much it shouldnt changes the ph much.
