Hey guys, I finally pulled the trigger and bought myself a 2006 YZ450F. I am absolutely in love with the bike. Now, the frame has a bunch of spots which look like corrosion. I've tried a few things to get rid of it (different polishes, cleaners, etc.). Does anybody know what I can do to get rid of them? Attached are a few pictures for reference. Thanks in advance. PS: I tried searching, however wasn't able to find anything.
