I have two Honda Accords and both have deep (white primer visible) but very thin (like hair) scratches in the rear quarter panel. I know a perfect repair is not possible without repainting the whole panel but a little touch-up paint would help a lot in making them less visible.

The red one was wetsanded by a professional due to other damage and it didn`t fix those deeper scratches.



I have limited experience with touch-up paint. I have found it to be very thick and difficult to use when repairing rock chips. What would happen with these very thin scratches?



I have bought a set of Langka but haven`t used it yet. Would it help me to put the right amount of paint inside the scratch and keep the factory paint around it intact?



Helpful advice to a newbie appreciated.
