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

["Paul Winchester" <bravo454@hotmail.com>]

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.
