I mostly use PC...and if there is an imperfection, I either metal braze it or use JB Weld...and PC sticks to both very well. PC has gotten A LOT better in the past few years with regard to the multitude of colors available, but occasionally they don't have the right color and then I'll paint it. PC is generally better for most mini bikers because it's A LOT more durable than paint (yes hard to 'touch up), and you drop it off, they SB it, and then PC it. Nice, easy process, and not terribly expensive. If you can't tell, I'm a big fan, lol...
