Thread: Black Cars Fingernail scratch

Dam Those Finger nail Scratches....
I got those on both my rides and I blame the ladies.....

Deep Scratches

A surface scratch that will `catch' your fingernail is approximately 0.04 Mil (1.0 µ) deep will usually require wet sanding and the clear coat refinishing Removing a scratch requires removing the layer of paint that contains the defect; you need to level the paint to the lowest point of the scratch. Removing more that 0.5 mil (12µ) of clear coat will cause premature paint film failure as UV protection percolates to the top of the clear coat. Check paint film thickness with a Paint Thickness Meter (PTG) before you attempt to remove

As you go over a deep scratch, the abrasives round off the edges of the high spots of the scratch. The result is a shallower scratch (when no full correction can be made) rounded edges don’t reflect light the same way a sharp edge will and is therefore less noticeable.
It may be necessary to carry out some localized wet sanding to facilitate full removal of any deep scratches, once again, paint thickness must be checked, and if the paint is too thin wet sanding should not be considered

Note: metallic paint is very difficult to match as the flakes won’t ‘lay down’ like OEM applied paint.

You won't be able to remove it by hand, chances are you need to find a buffer / wet sand. Wet sanding on the extreme end of the spectrum. I would find a detailer to do it for you.

I don't know where you are in MI but hit up Auto Lavish

Thank you all..

again yes you can remove it by hand. Not sure why you would think you couldn't. A fingernail scratch is nothing more than a marring. a dab of 105 on an MF towel will wipe it right off. If need be I'll take pics tomorrow of it (maybe a vid considering it takes all of 10 seconds to complete from start to finish LOL) they are really unsightly I know but extreamly easy to get rid of.

he scratch x did not work, what is the 105, I would like to use something stronger like compund, can I?

You can 105 is just a fine buffing compound.
