    Ill make this a quick guide and for the most part its all pretty easy to do with some spare time on your hands.

    Total cost supply cost: $30.00


    Materials:
    - Any Aluminum, steel or metal parts
    - Mothers Mag and Aluminum polish
    - Microfiber rags
    - Buffer (if you have one, or just use a makeshift one haha like myn)
    - 120, 220, 400, 800 grit wet/dry sand paper
    - Soapy water/ Rag

    Alright so first just make sure you have your supply's as seen below. Its all pretty cheap for the most part.



    Next, take whatever muffler,piping, or metal piece you are polishing and wipe down with soapy water and a rag then dry off. In this case im using a friends magnaflows that i bought which look like crap.
    Few Pictures:









    Now start with a low grit paper to rough it all up. I used 120 then moved up to 220 to 400 then finally to 800. You may go higher for a cleaner finish but im lazy and this part wont really be seen so im fine with 800.




    Yay, now that your finished with the boring sanding you may take your Mothers polish or whatever else your using for metal and get to rubbing it in. No need to destroy your arms if you dont have a buffer so just rub it in lightly. Black residue will come off, but this is a good sign its working even on the shinier parts. Simply just rub in then wipe off as if you were buffing anything else.
    Make sure you have a microfiber cloth...it helps more then you think to pick up the excess gunk without smearing.




    Getting there..... about 3 coats in.



    After like 4 coats i was tired of using my arm and i dont have a buffer so hears my alternative which actually worked well haha. (Not required)
    Cheap Buffer= DA sander+ Microfiber cloth





    Once your happy with how it looks stop and give it one clean wipe down and your set. Here's how myn turned out and this is my first time polishing metal but not to bad. At least it will look decent when i install it soon.

    Not Perfect but im happy with the glossy loock now.
    To rid sanding lines go higher grit and spend more time
