Oh hey, I forgot to mention it but you should really wax your frame before you build it up. I noticed that on my lighter coloured frame that scuffs really show up unless you wax it. I know you have a black frame but it still couldn't hurt, I have two black powder-coated frames (from Spectrum too) and they also got waxsed. I think I used Turtle car wax or something similar. Cheers.
