A. I found this, maybe it will help. Remove all the bodywork from your bike including the tank. This will save expensive plastic from any accidental slips of the sandpaper. Before you remove the bodywork take note of what parts of the frame are actually visible. No reason to polish something that will not be seen. Then start with 220 grit sandpaper to remove the anodizing from every where that you want to shine. What is important is to go always in the same direction with the sandpaper strokes. Try to go with the existing "grain" of the metal. Removing the anodizing is a long pain in the ass process. You will have no finger prints left after polishing. From 220 comes 320 to remove the scratches left from 220. I recommend wet sanding all the grits. Wet sanding will help to keep your work area clean and it makes a big difference with the higher grits. The grit sequences I use are as follows: 220, 320, 400, 600, 800, 1000, 1500 and if needed 2000. Doing the whole bike by yourself with a good part of everyday dedicated to it will take just over a week. If you don't mind investing some money into this project buy an orbital sander. This will greatly reduce the polishing time and wear on your fingers. When you have completely removed all the anodizing and pits, redo 220 by hand to remove all the swirls left by the sander. If you decide to use the sander only use it for the first grit. The only "trick" involved is not to get into a rush to complete it. I really can not stress this enough. If you do not completely remove the scratches left behind from the previous grit you will always have scratches visible. When ever I think I am finished with one grit I always go over that same area again one more time with a fresh piece of paper to ensure I have all the scratches out. I recommend to keep using the same piece of paper until it is smooth so you are using it to gradually remove the scratches left from a fresh piece of paper.

You asked about coating it to avoid oxidation. I have seen people who have tried to clear coat a polished frame with little success. I am not a painter but the way it was explained to me is that the polished frame is now very smooth. Special paint is needed so that is will actually stick. The ones I saw painted looked very dull. If you have any success with this I would appreciate any knowledge gained. Up keep of a polished frame is not difficult though. I use a metal polish called Mothers [ ⇦ this on eBay or Amazon [affil links] ] but I have used a product from Europe called "Wenol" ⇦ this on eBay or Amazon [affil links] that was also good. When I get caught in the rain I just dry the frame and swing-arm to prevent any drops leaving rings when they dry. And when I clean the bike I just go over the bike with the metal polish to bring back the mirror shine.

I hope this babbling letter helps you. Time for me to go grab another beer and check out some more bike web sites. I hope that you do polish your frame and swing-arm. I believe it adds to the pride of ownership. Plus it is great to see the look of other people when they see your bike. :) Best of luck to ya! ~ Nick

A. Just one more piece of advice on this subject, not all frames are anodized, many are just painted. If it is just painted you can simply use Aircraft Stripper to take the paint off. Make sure you use the brush on kind and not the aerosol. DO NOT GET ANY ON PAINT YOU WANT TO STAY OR ON PLASTIC! This stuff will eat plastic, and any paint that it touches is coming off. I polish out frames, and do other custom bike work for a living. This step will save you a crazy amount of time. But just take your time, get some buddies to work with you and get 'r done!

A. I am not familiar with that bike, but it's not anodized unless it's made of aluminum. So step one is to see if it's magnetic; if it is, it's steel, not aluminum, which in turn means it's not anodized.

A. Frames, you can polish a frame over the weekend...
First, if your frame looks like brushed aluminum..its anodized Aluminum...if its a solid gray, black, silver ETC, its painted or powder coated.

Do not sand anodizing off of your frame, its the hardest man made substance on the planet and you will waste a ton of time, and a bunch of sandpaper sanding it off. Go get you some heavy duty strength easy off oven cleaner ⇦ this on eBay or Amazon [affil links] , it has just enough acid in it to remove anodizing.... I spray it into a bowl and then brush it on for better control. You will want to cover your engine, and everything else you do not plan on polishing with plastic, or garbage bags.

First, with the body on the bike...make marks on the frame where it becomes visible at all points, so you know what parts of it need polished. I recommend ONLY polishing parts off the frame that you can see, because those are the parts you can also easily care for...removing anodizing exposes aluminum to the weather...so it needs protecting with Mothers, or a car wax...the same as your paint does.

Now, remove the body, put plastic over everything to are not going to polish, and then brush on the easy off oven cleaner...let it set for about 20 minutes, wipe it off and then coat it again...let it set another 20 minutes...then wash the frame with warm soapy water. Do not worry when you see the frame turn black...it is just part of the process.

Next comes the sanding...and yes I really do recommend a palm sander for this, it will cut your sanding time by a multiple of 10.

By wet/dry sandpaper...start with around a 400 grit..and move to the next higher grade, do not miss any grades...and take your time, do it right...the smoother you get it, the better the result! sand all the way to 2000 grit...

Wash the frame again to make sure no sand grit is left on it.

Once you have the frame smooth from sanding, it should feel EXTREMELY smooth, like glass. It is time to polish, I use 4" vertical buffing pads (the string type) on a grinder.

Start with a cutting compound...get the brown, it cuts the best....again, take your time for the best results. Once you have polished the whole frame with the brown...wash it with dawn, put a new buffing pad on your grander, and color with red jeweler's rouge ⇦ this on eBay or Amazon [affil links] buffing compound....and again, take your time.

You should have a mirror like frame now....

Hope this helped...good luck!

A. I have personally polished my 02 YZF R-1 by hand. My suggestion to all that would think that this is a good idea would be to try to have it dipped, seriously. You have to seriously go over everything with each grain of wet sandpaper from 180 to 2500+ from one to the next. Then I burned up three dremels and a bunch of jewelers rouge and Mothers. I did everything possible from the triple tree to the speed fasteners that hold the plastics on to the freaking pegs ... all the visible bolts and covers too. And trust me if you get that far there's no way you're gonna do the wheels unless you're really nuts. Well at least I wasn't gonna. I've seen some of my friends try but I've yet to see any that have turned out really good. If you're a perfectionist plan on turning down your whole bike and if you're not do not attempt -- you'll end up looking like a poser with 6 inches on possibly both sides of your frame done looking for someone to finish for you, lol.

A. RE: forks shine:
I got a couple different grit scotch brite pads that go on a drill motor used them to strip the clear coat pits and oxidation, then used blue diamond and Gord's ⇦ this on eBay or Amazon [affil links] . they look great, but not quite like chrome yet. My next step will be wet sanding, but I will start with 1000 grit and work up. both previously mentioned polishes leave a protective coating.
Avoid clear coat as it chips easily and looks terrible.

I HAVE STARTED THE PROCESS THAT STEVE POSTED AND IT TAKES NO TIME TO GO THRU THIS PROJECT, BUT IF YOU TAKE THE ADVICE PLEASE USE RUBBER rubber gloves ⇦ this on eBay or Amazon [affil links] , THE OVEN CLEANER WILL LEAVE CHEMICAL BURNS ON YOUR SKIN ... SUCKS. OTHER THAN THAT YOUR STEP BY STEP INSTRUCTIONS ARE WORKING LIKE A CHAMP, THANKS BROTHER,
