What methods are yal using for creating highlights where there originally were none?

I am especially curious about highlights that curve along with the lines of the car.. like thin highlights as if created from a kino flo.

im thinking something along the lines of gradients? create a selection of where you want the highlight and do something with gradients? probably many layers at different opacities/ masking?..

can any wise ones out there 'shed some light' on this? DS_Naughty2.gif

couldnt find any helpful tutorials but if anyone knows of a good one i would love to see it thumbs_up.gif
