The already smooth spots I just sanded with 2000 grit, then 3000 and then Adams Metal Polish #1 and then #2. Sanding with 2000 grit ensured that I got all scratches off that I did not notice.
Ok so i received adams metal polishes 1 and 2 today. I had some time to work on one wheel a bit. I went ahead and cleaned it using deep wheel cleaner (i noticed no purple this time either), and after drying them up, I used metal polish number #1 along with a new blue microfiber applicator sponge. I followed this video as a guide
To remove the forging lines I used 320 grit in some places, but the 600 grit worked well for most of the rough spots. Then I sanded these locations with 1000, then 1500, then 2000, then 3000, then Adams Metal Polish #1 and then #2.
Also, i went ahead and used adams metal polish #2 after #1 was cleaned up but i didnt notice much of a difference at all. I kinda expected #2 to make the shine stand out, but I dont see much of a difference. Any tips on how to make it a bit shinier?
