    How to polish that part, for beginners

    Hi everyone, I've gotten alot of e-mails from my website about polishing. I thought I'd post this so anyone who is a Do-it-yourselfer can polish at home.

    First off, I'd like to say that any and all supplies can be ordered from www.eastwood.com. They are the the best suppliers for polishing needs I can find.

    Ok, so you have an engine cover that is looking bad. No problem, polishing is pretty simple. I'll use a worst case example as well.

    You have an engine cover, left side. You or someone turned the bike over and gouged the aluminum. The finish also happens to have a coat of that old, yellowed clearcoat on it too, and to top it off, it's badly oxidized.

    First thing, go to Wal-mart and buy a can of "aircraft stripper", and a set of rubber gloves.

    Scrub the part with some #00 steel wool to break the surface, it allows the stripper to sink in under the clearcoat better. Spray the part thoroughly and let sit, you'll see the clearcoat start bubbling, just make sure you do this OUTSIDE. Also, this stuff is HOT, it'll burn you chemically.

    Ok, so the clearcoat is off, easier than you thought. Now the cutting begins. If you have deep gouges you just get some 600 grit sandpaper and get busy, work your way up to at least 800. Not every gouge is removable, they're just too deep.

    Now come the 'emery' compound and 'sisal' wheel. This will remove oxidation as well. This compound 'cuts', but don't expect it to do alot quickly. Take your time and don't push the part against the wheel very hard.

    Now the polishing begins, you'll need 'tripoli' compound and a 'spiral sewn' wheel for this stage. Most beginners can start at this stage if the parts aren't bad, or have a factory finish. Take in mind that even if you have a factory finish, aluminum oxidation will require an 'emery' type grit to remove it.

    'tripoli' finishes are sufficient for most people, it's easy to maintain as well. But let's get to the real mirror finish.

    Ok, the finish, and this is when your part will emerge beautifully. You'll need the 'white rouge' compound. This part is called 'coloring', as opposed to buffing. You'll need a 'canton flannel' wheel for this. With rouge, you need very light pressure on the part, don't let the part get hot! It changes the 'color' of finish.

    Ok, so that's it. But you must remember this:

    Use only 1 compound per wheel, NEVER, EVER, MIX.

    A cool part polishes better, the compound doesn't 'cake', you can alternate parts on a wheel for this, letting each one cool by a fan.

    Use cotton gloves, your hand oil can drastically alter the coumpounds' effectiveness. My guys have 'grit gloves' a pair for every grit. Nothing sucks worse than coloring with rouge, and seeing you have to take out emery scratches.

    Wrap a towel around the base of the buffing motor, and put an old blanket on the floor, beleive me on this: A PART WILL FLY OUT OF YOUR HAND, it's inevitable, bet on it.

    A bench grinder motor will work. 1HP is optimal, 1/4hp is hard but doable. There are websites on how to set-up your own polishing motor from a used dryer motor, if that attracts you. You need no less than 3400 rpm to polish, any less isn't possible.

    Touch the compound to the wheel often, what I train my guys to do is stand in front of the wheel and hit it with the compound, when you feel dusty-like bits touch your face, then it's enough. Wearing safety glasses of course.

    Always clean the part between grits, always. Just use a clean WHITE rag.

    When you get to the Tripoli and White Rouge grits, the parts have to be wiped with a clean cotton material and white all-purpose flour. the flour soaks up oil microscopically, and doesn't scratch a surface.

    Don't ever blow a part clean with compressor air, compressors air has oil in them, whether you see it or not.

    AND MOST IMPORTANTLY, ALUMINUM OXIDE IS A DIRECT CAUSE OF ALZHEIMER"S DISEASE, wear mask or wet bandanna, they're CHEAP.

    I hope this helps guys. It seems like alot, but when you start you'll see it's pretty simple.

            any experience with this "heavy metal" polish? I am a big fan of the "green" liquid compound that they carry.



            i have polished quite a few gun barrels with their compounds, and have always been pleased with the results.

              Me: Hey Dan-O. Just wanted to say howdy & love ya!

              Dan-O: Howdy and Love you too. Doing good, feeling good.

              Me: Give 'em hell, Little Bro!

              Dan-O: Roger that! :)

                i have polished quite a few gun barrels with their compounds, and have always been pleased with the results.
                For guns, try the Tripoli with a loose spiral wheel, works like a dream and takes about 2 minutes for a whole rusted rifle, and the blueing stays. (My company does gun finishing too)

                But, I have to say I haven't used that kind of compound.

                What those kind of companies won't ever do, is say what kind of finish you'll end up with (i.e.: #1 or #4?). A factory finish, glaze, or mirror? I'm sure it's probably good for oxidation, but only for above surface.

                When a part has in-grained imperfections, meaning that the oxidation is level or even lower than the surface around it, liquid chemicals simply can't work. They can't wear out or melt metal, this is why:

                Oxidized aluminum is like a 2-by-4 laying on the ground. When you turn it over you'll see the termites have eaten along INTO the suface, making line cavities in the wood. You would have to literally sand ALL the wood even with the level of the termite damage to 'remove' the imperfections.

                Aluminum is the same way. If the oxidation were to just dissapear from the metal, you'll end up with alot of ugly pitting.

                Buying a liquid compoind for 19.95 is more expensive than buying 2 compounds and 2 wheels, and less effective. Most polishing just needs Tripoli and White rouge. And the compounds/wheels will literallly last you for YEARS, not to mention enormous amounts of time and labor.

                  Cassius, send me 1 part, like an engine cover or master cylinder, I'll polish it to a perfect mirror finish for free.

                    good info. i checked out the "kit" that they were selling on the site you linked. Think i am going to pick it up. just can't decide if i want to go the drill or bench grinder route.

                      OY! Make sure you go with the bench grinder kit. Drills don't spin fast enough and get hot easily, they'll burn out quickly. You need 3400 rpm min. 4000rpms are great.

                      What you can do, and what I forgot to mention above is get the bench kit, or any wheel, and mount them on an angle grinder. You can then polish or maintian a shine on your bike(s) without removing parts.

                      Also, you can clamp an angle grinder in a vise and use it that way. Handy because you can work all sorts of angles.

                      A very nice option too is to get the 1/4(?) polishing bits, dirt cheap and great on a die grinder for nooks and crannies. Don't waste money on Dremmel bits, they last about 3 seconds.

                          This ice storm hit us pretty bad, we weren't out of power for very long but we were down for 2 full days, and already backlogged on orders to begin with.

                          We're starting to get our heads above water and I'll update you very soon. They are pretty rough and the oxidation is very deep, but they'll get done, and you won't even recognize them.
