Default polishing aluminum...

just wondering if you can use a dremel to sand it or is it better by hand? do you just sand with a rougher grit and work your way up to a finer grit paper and then polish? thanks

the dremel was real dicey, then again mine only had one speed, If you had the variable speed one......might work better, but to get the whole surface uniform would be a PITA. would probably work better for trouble spots and in hard to reach areas

It depends on the size of the aluminum.

I usually use the dremel in tight areas or really rough areas, and then hand sand.

I've had better results by hand and a sanding block. Keeps things nice and uniform. A dremel comes in handy for those hard to reach places or sanding down large casting marks.

I only use a dremel is tight spaces as mentioned. If I try to use it on a larger area I get high and low spots that are very noticable when finished.

could you use the dremel on it first then finish it off by hand with a fine grit?

Sure...if you have a really steady hand. Chances are, when you're finished you'll notice some high and low spots. The fine grit may not be enough to smooth everything out.

What are you trying to polish?

Basic sanding tips: You have to get down to 600+ before you use a drill/attachment/tripoli.

When you sand start with 220/320 and go in one direction untill everything is perfect in one direction. Then go to 400 grit in the 90 degree opposite. Sand untill the previous direction's sanding marks are gone.

Continue the 90 degree change with 600 grit and then start with a drill/dremel/buffer.

Along these same lines, is there a good polish for all metals - specifically aluminum, high carbon steel, and possibly stainless?

I've got some high carbon steel that I'd like to polish up, but would like to only have to buy 1 polish for that and some aluminum.

^^^ Tripoli. (Check Eastwood==>)

It's a brick-like compound that you hold to the buffing wheel for a half second. The heat will melt a bit of it onto the buffer.

The polish/shine will only be as good as the sanding job beneath it. (Like auto painting)

85% of the work revolves around sanding.

Chrome whatever you want to polish! Polish is a pain in the rear. Everything that was ever polished on my car or 3 bikes eventually was sent out and chrome plated. So much easier to clean and looks nicer. Takes the fun outta cleaning my car when i have 20 polished pieces that are all cloudy and need lots of TLC , then look like crap 5 days later anyway. My car is a daily driver though and see all weather.
