Has anyone ever eaten dry cardboard or chewed on aluminum foil?
You will first need to sand the material around the scratch down to the same level as the scratchHow course a grade of sandpaper to use depends on deepness of scratch and how long you want to sandGet a range of papers from say, 100 to 1000Go from course to the finer paper, the brushed look will be the result of sanding in one direction only (for instance right to left) for the final sanding Go with the direction and grade of sandpaper that blends the area you fixed in with the rest of the bicycleYou must practice this on another piece of alumbefore doing your frameAlso remember although your bike will be better without scratches, you are removing material, , it will be difficult to make things look really good, and any areas you work will appear brighter until an alum oxide layer formsA dremel with fine frizzy steel wool type attachment may also be good for the final step where you are replicating the brushing.
NO NO NO! Do NOT sand an aluminum frame to rebrush itRaw finish aluminum is anodizedsanding will provide a way for moisture to creep onto the bare metal and turn it blackYuckI suggest that you live with the scratchesIf you ABSOLUTELY have to and will live with the black metal then use a coarse Scotchbrite padEDIT: I am sure that those who gave me thumbs down know that aluminum reacts differently than titanium and that aluminum can NOT be placed outdoors without it turning uglyI am equally sure that the same people know that if an aluminum frame isn't painted, it is anodized, and the anodizing can be removed by sanding or scotchbriteor even oven cleanerSooo, just because you don't like the answer doesn't mean it isn't correct.
Scotch brite pad, but make sure you follow the grain.
dry cardboard whenever the kids order pizza and give me a slice aluminum foil when I didn't completly unwrap left overs
