Marks after stripping

[OldAngler]

I recently bought Speedia knowing in advance that the paint was in poor condition.

I have stripped the paint using Dettol and a toothbrush and spent several hours rubbing down with fine and extra fine wire wool. There are grey marks on the surface of the Aluminium. See photo.

Three questions:
1.Is this the best I can hope for and I have to accept this finish?

2. Do I need to rub down further with wire wool?

3. Is there an easier, possibly chemical, method of removing these marks?

Thank you, Old Angler

Yes that looks like pitting of the metal surface. Not much you can do other than removing metal.

I decided to persevere with 600 grade wet and dry sandpaper and steel wool.
The final result is not perfect but 'satisfactory' and I am happy with it. It is certainly better than it was.
Oddly the back plate, which had the worse marks, has come up cleaner than the drum.
