Hey, this question is for all those who are/have prepped their own car for a paint job or know how to do so...The question is on my car, 90 240sx, theres a line about 3/4 centimeter wide along the whole car, and i had to get a huge dent out which meant bending the line out of its original shape. I can't seem to fix it to the way it used to be no matter how much sanding i do...Any pointers would be greatly appreciated. thanks
