Will.. I have had a great deal of experiance with Line X, and the best way is to let them try to match the color with the product (and they wont) then have it painted over with the correct color. Should you get a chip or small scratch the colored pigment will show and not look so bad. You will be surprised how well it holds up painted!

Thanks for the reply. When you say they won't match the color with the product do you mean they won't try or it won't come out very close to the color of the paint on my truck?

They can come close but it will not match exactly. Again, use a primer as close to the color of the final paint, then chips wont stand out near as badly.
Same concept. They will try to match, I just have not found them to be close enough for me. You may get lucky. I had a plate of steel sprayed with line X and then painted stripes on it in white and red... One year later and 400cars a day it still looks good. Get up close and it has some wear, but what wouldn't? I am not thinking your rocker panels will have any issue holding up.
