Any soft-plastic scratches are going to stand out. And your always going to get more. :furious:
I use the finest (lightest bite) nail file (I ask my girl to save her old/worn ones), and 'brush' any rough edges off. This is done with all the delicate finesse I possess, not touching anywhere but the scratch. With a round metal cylinder I'll press and roll the area firmly to 'squeeze' the gouge enough to round out the sharp edges. Sharp, rough edges stand out more than smoothed, rounded imperfections.
I know this next step isn't what most will subscribe to, but I will lightly Q-Tip the scratches with WD-40 and rub it in. In my opinion, this 'seems' to hide the color difference in the scratch.
(This is where true 'plastic guru's' will know where to use different thinner's and acetone's to manipulate the plastic and beyond my knowledge - so you're stuck with my silly routine.)
Then I'll go over the whole car with interior detailing finish.
You're always going to see them, but the cleaner and less pronounced they are, the easier it will be to live with them.
Good luck ... hope this helps!
