Right way of using wetsand to remove certain scratches?

[TrustJesus]

Hello AG, good day.

I want to grasp the concept why some scratches will only improve using wetsand?

Can someone educate me on when to start wet sand to improve a scratch in general?

Some scratches are too deep for a mild compound tio effectively grind smooth. Sandpaper may knock the edge down. In some cases, it may be better to leave a deep scratch than try to level it completely. You sand through the clear you are SOL.

Would having a paint thickness gauge help to keep clear coat in check?

Based on what I've read before, if you can feel a scratch with your fingernail, it's probably too deep to safely remove. I really can't comment as to how effective a paint thickness reader would be in this type of situation.

Got it, thanks for your time.

My suggestion: If you aren’t experienced at sanding, don’t do it ....especially on factory clear coat. You are better off living with some scratches that sanding thru clear coat.

What you are doing is leveling the rough edges surrounding the scratch. If the scratch is only penetrating the clear coat, then wet sanding will level the scratch and compounding/polishing will remove the sanding marks.

If you can feel the scratch with your finger nail then you need to use touch up paint to fill the void. Filling a scratch is an art in itself. Takes multiple coats over several days. You don't want to apply too much base coat as you need to build up with clear coat. Exception, is if your using a base coat, clear coat mix.

Sounds good, I got it now.
