how smoothed do you want them? like just the rubstrip at the top smoothed and coded or like full on indicators and swage line smoothed?
do it yourself, im smoothing mine as we speak and i have no experience with filler or plastic welding or very much spraying, just look up tutorials on plastic welding (theres a VERY good one on clubpolo by someone who smoothed his 6n 16v bumper but its all the same, just take the ideas and principals off that onto yours)
