Okay, so i've been thinking about grinding my rim... my Local bike shop owner told me not to, because it will weaken it... i know all you guys, or most of you guys use grinds. But i've been thinking, and i tested this out, i found a Wirebrust attachment to a drill, and used that to scruff up my rim, kinda of like a really light grind, i think you casn find these wire brushes in different textures, to make a lighter, or hard grind.
This is a pic of the wire brush
and this is my rim after.
Personally i think i'm going to use it just so my tar will rub on my rim better, but try it and tell me what you think, If you find out about these wire brushes post about it, if there are other textures or hardnesses.
