For the first time today actually cleaned and polished/buffed the side rails on a game - wow - what a huge difference that makes!
Respray over the Easter long weekend! 
You mean you buffed instead of re grained ? so do they have a high shine ?
I applied that stuff in the green bottle with the crock on the outside (name slipped my mind) and then scrubbed with a toothbrush. After leaving it there for 10 minutes then scrubbed down the 'grain' with an old scotch cleaner thingy. After that used an old shirt to take off the excess then buffed and it looks awesome. Will take pix after the spray job is complete on Monday/Tuesday 
So you have regrained it. The "green bottle" is Isocol
Next time - Try this - 320 Grit Wet/Dry and Windex. Use a soft block and with straight lines. It will look exactly as it did the day it rolled off the assembly line. I usually take the side rails off and use a "straight edge", so that the "grain" is dead straight. I then use new nails. Takes time, but the results are always rewarding
