Trust me, I know about shipping cost to this corner of the country...lol.
I'm actually trying to work out a shipping plan or something for customers to increase sales.
Either way, when it comes to getting rid of the curb rashes properly, there are many techniques, but the fact is that material is gone, so you have to 'grind' down the high spots to even everything off.
Therefore the trick is to grind down to the lowest point of the 'groove' ( hope that made sense )
The other trick is to now make the rim even all the way around which involves grinding uncurb parts of the rim. This is done to help balance the rim as well as keep it looking good.
Just imagine a rim on a balance machine and while it's spinning, all you see is continuous waves....lol
That by itself is a process using various grits of sand paper, or flap disks on an angle grinder with surgeon like hands. When it comes to the polishing, it's almost the same process, but with much higher grit sand paper and rubbing and polishing compounds.
If you want a professional finish, it take alot of time and patience.
