OK not sure if I want to get involved but here it goes. DO NOT USE 150 on the tank â€"œ you will ruin your tank!
To polish you need is cerium oxide but before you can start you need to find out how deep the scratches are. Just run your finger nail across the scratch if you can feel it then it’s too deep to polish out and you will have to grind out the scratches. The grit used to grind out the scratches on glass will depend on how deep the scratches are and I normally start with 2000 (Two thousand) grit. If that isn’t working then I’d go to either 1200 or 1500 grit. If that seems to be working then go back to the 2000 because the 1200/1500 will leave scratches. Once all the scratches are out then it’s time to use the cerium oxide.
Also- just to let you know you also can use the black sandpaper at Lowes/HomeDepot (I’ve not used this but have heard you can) which you need to use with water. Then same as above go finer and finer with the grit until it’s ready to polish.
When you mix the cerium oxide, mix it with water to the point it looks kind of milky. Put this on a buffing pad and the harder the pad the better (leather, felt etc). You need to keep the area wet so I either use a spray bottle with water â€"œ or I use a wet bet sander. This is just a run down on the process.
This is one of those posts that I copy and paste in my documents. You never know when you may need this info. I had never heard of cerium oxide before, so I did a little Google on it. Amazing stuff it seems. Thanks Carol!!!:rollface:<a href=showthread.php?s=&postid=10059448#post10059448 target=_blank>Originally posted</a> by ReefArtist
