What am I doing wrong with wetsanding CC?

I'm trying to wetsand my clear coat down a bit because it has really heavy orange peel, highs and lows, when I wetsand though I am washing the spot im going to sand, rinsing and then using 1,000-1,200 paper. I tried to use the block but the panel has a lot of curves.

I noticed when sanding its driving these white speckles into the paint and kind of pitting them in. I'm not sure if this is clear or sand paper grit getting drived in

I'm using normal town water you get out of a garden hose. I have tried spraying with one hand and sanding with the other to keep the spot wet. And tried frequently washing the sand paper and panel to remove the build up.

Am I pressing to hard on the block/sand paper?

Any advice?

You've got solvent pop or solvent entrapment. No way to correct other that to sand and refinish. If you don't, you'll always see those specs. The voids will fill with compound.

**** that's from the base coat right? I did put the clear on way to soon.

You need to let the base coat flash off with more time before clear.

Yes, it is from base coat.

I wouldn't say it's necessarily from the base. Improper range activators and reducers combined with heavy application are common causes. Exposing the panel to sunlight too soon after spraying seems to cause it also.

Some clears are more prone than others. I can spray cases of some clears with the same activators year round without issue. I try others, and have pinholes show in the clear on the first job. Ultimately, it comes down to what products work for you.
