i tried wetsanding for the first time to take out a few scratches, they were from using a cheap rubbing compound:P i ended up wetsanding the entire panel with #2000 grit 3M sandpaper, i didnt have anything finer than that so i didnt proceed 2000 with anything else.

i used a 4" orange pad and m105 on my GG DA polisher (speed 6), it took out the wet sanding marks to a point where you cant see them if youre 2-3 feet away, but upon closer inspection theyre all over. i see all these little "ripple-marks" going in one direction.

the car is a black honda civic, i hear the clear is soft. should i be able to take out 2000 grit sanding marks with m105, an orange pad, and my GG DA?

i guess ill have to find some 2500 grit locally to follow up the 2000 with.

Have you hit it with polish yet? If yes, hit it with the 105 again, or something with aggresivness inbetween 105 and polish, like meg's #2.

Then polish again.

yes i followed with m205 on a white pad, no difference. i think theyd come out if i was using a wool pad and a rotary

Probably. How clean is the pad you are using? How much product are you using?
 
I was able to get 2000 grit sanding marks out of a panel using Ultimate Compound and an orange GG polishing pad with a PC7424xp on speed 5. Sometimes it took a second run at it to remove them all.
 
speed 6 is to fast try 4 or 5 i used the orange lc pad and 105 and my sanding marks came out.
 
First... make sure your pad is rotating, mark your backing plate if you haven''t already. It's when the pad is rotating that paint is removed best.

Second, move the polisher s-l-o-w-l-y over the paint, you need to give the combination of abrasives, aggressive pad and rotating/oscillating action to do their work.

Third, if need be, shrink your work area downward in size and really focus on the task at hand.

If this is a factory baked-on finish then removing scratches can be a challenge due to the paint hardness factor.

You might have to get a fiber pad like a Meguiar's Microfiber pad or a Surbuf pad.

Rsurfer is also correct in that if you continue to have difficulty removing the sanding marks then you have two options,

  • Finish out at a higher grit
  • Switch to a rotary buffer

thank you mike for your detailed response, much appreciated. yes im doing all of the above, going over the sanding marks slowly, i was using 4" pads so they were rotating quickly. i think i just need to finish with a higher grit, ill try ending with 2500 and see if that does the trick.
