RedBaron,

First off using an 8" angle grinder to get in between the spokes on a MC wheel is going to be a good trick. Now if you were to use a 3" - 4" wheel on a drill motor you would in all likely hood have and easier task.
Rule of thumb: If the aluminum is smooth and you can't catch the scratches with your fingernail just polish it! If you have scratches that you can catch with your fingernail sand/wet sand up to 400 grit.
Why? The black compound (Emory) is about 400 grit.
How long do you use the Emory, until it doesn't give you any higher luster, then switch to a new buff and use tripoli or white!
Clean your buffs ofter.
If you have sanded up to 1500 grit I would start with white compound on a sewn buff and see if that will give you the luster that you are looking for. If not back up to Tripoli on a sewn buff. Finish with white on a loose buff.
If you buy the Zoopseal kit you can mix as little as you want and save the rest for another project. Two weeks in the frig. AFTER MIXING is right. I use a little atomizer bottle to apply mine it works good.
