After stripping and priming my F6 grill teeth, I'm noticing minor stretch wrinkles from when the metal was originally formed (The teeth have no dents or trauma.). Are the indentations acceptable or do I need to fill them?

 

All of mine are that way on the rear, under the grille bar.

 

Yes, under the grill bar. Then painting them without filling will be stock, just like the original. Thank you, Ross. -John
