Looks good but I would not have taken the YAMAHA OFF because it looks sick when it is polished and still has the YAMAHA on it, but different strokes for different oukes
i did mine also but left the yamaha on. i used a wire wheel on my cordless drill and some super fine steel wool. took less than half hour and looks good.
what else might look nice make it all shiny then go over the yamaha writing in black or some color to match you quad an leave rest shiny then put a clear coat that could look sick
i just did mine the other day. i left the yamaha on but couldnt find the wire brush for the drill so i used a hand held one. i couldnt use samdpaper to get in the letters. it was tough, took about 30min.
