If you do not have the proper tools, or the additional ambition needed to compensate for lack thereof, consider contacting a local metal plater. I would think they would be able to polish them for you, or even chrome them.
Stainless is much more difficult to polish than aluminum for the DIY'er. I had a Bassani stainless tip that was badly gouged during shipping. I used a palm sander to sand them out, going from ~150 grit to ~800 grit. Then I used emery/Tripoli at a buffing station (converted bench grinder) and then white rouge. Turned out perfect. On the other hand, I tried polishing the inner lip of some all stainless Corsa clones because they were never prepped properly. Since I had no abrasive attachments that could rapidly and smoothly remove material, I sanded by hand forever and a day, and still could not make it chrome-like after buffing.

We are at a disadvantage to the shops. I have some helpful tools, but I do not have the crazy helpful stuff the shops have. I think I remember ~Joshua mentioning that he used a 10hp buffing station with great big honkin wheels. I feel fortunate to have a 1hp bench grinder I can use as a buffing station. The “pros” probably have a veritable arsenal of tools and accessories to do the prep work. Stuff like numerous sizes and grits of flap wheels and low grit compound/wheels can really speed up the prep work. Good luck.

If you want mirror-like results doing it by hand is not an option.
For under $15 you can get your tips looking almost perfect.
What grits do you have?
Do you have any air tools or a drill?
As far as a bench grinder, it's the best polishing tool I've used.
However, you're limited to the areas you can reach with a bench grinder, a 6" wheel won't fit into small spaces.

That's good that you have the paper. I usually sand up to 1000 for stainless.
Just like bsf said, it's all in the prep. Take your time sanding in alternating directions between grits.
Check out Eastwood's (sponsor -->) tech library under buffing.
It's worth the 15 minute read and they have excellent starter buffing kits.
If you don't want to go through Eastwood PM me.

Stainless is a very hard metal, it can be done with sandpaper and a bench grinder, but it will take forever to get good results. Most shops use large machines, usually 15hp and large buffing wheels, 14-16 buffs. The compounds used aren't generally purchased at your local hardware stores. Here is some stainless I recently done, 15hp machine with a 16" buff. Sand it once, and buff it twice.
