It saves time, but it's pretty easy to mess up a part with a polishing wheel. (I know this from doing chrome many years ago -The wheel can leave serious buffing marks.)

- I am confident in Khatfull's more conservative methods, and definitely uncomfortable with the Dremel /Black and Decker sander etc. recommended on that BMX site.
- If anyone has not read Khatfull's post carefully, and in its entirety, you owe it to yourself to do so now.

Excellent treatise Khatfull! Thanks!
