Just cleaned up the rear wheel with aluminum foil and while I will still say it works 'good' and does not scratch up the chrome it will not replace chrome on places where there is deep rust. 
I put on a 46 tooth (stock is 40) and so far it feels much better. I will ride it to work and have a better idea after that. sure is fun! Spun the rear tire in my gravel driveway! WooHoo! 
I forgot to try it...I'll have to write it down right now, then find something chrome around here.
