There's a lot of lug polishing going around now, but it's a lot of hard, time consuming work. I used to build a lot of frames that would get chrome lugs and stays. It's more labor intensive for stainless than it is for prepping for chrome, and a very dirty job. Now if I need shiny lugs I use stainless steel. Here's a fork crown and stem I'm polishing right now. If anyone wants to see the lugs before paint I'll find the pictures and post them also. I prime the work before polishing and buffing. I then strip the primer, re-prime, and paint. After paint I give it a final buff and it gets real shiny. You might have to click the image to get it to look right.
