Hi all.

I have no clue where is most appropriate to ask this, but I'm guessing in this sub-forum is as close as it gets.

It's simple. I have 2 aluminium sheets of 0.25 square meter each. I want to have them polished to a mirror-like finish. Where can I have this done?

Preferably around Batu Caves or Sentul area. And it's unlikely I have the budget to buying a polish machine myself.

I have tried pretty much all.
I bought polishing liquid and sandpaper. I sandpapered all old scratches off the surface and tried polishing with cloth+rubbing but it does not give good results. Not at all so shiny.
The shopkeeper was not very useful in giving me information on this, hence I came here.
Also, how do you suppose I attach a sponge to a drill? Once I apply a little bit of force on the sponge, the drill just turns independently from the sponge?
Buying a mirror also will not help because my aluminium surfaces will be curved.
