Hi all,

i was really stupid and i forgot to wet sand with 3000 sand paper when trying to finish correcting some paint. Instead, i dry sanded with 3000 grit paper. After compounding and polishing, the clear coat became clear, but not perfect. when looking at it within 1feet, i can see the sand marks still. Has this every happened to anyone and how did they fix it?

thanks in advanced!

There is not much difference between wet sanding and dry sanding in the end results. The benefit in wet sanding vrs. dry is no dusting and limited loading of the paper.

It sounds like your compounding did not get rid of the 3000 scratches. Get some better lighting.

You can compound with a heavier compound or sand with maybe 5000 grit.

Like Ron said, not going to be much difference in end-results from dry sanding versus wet sanding with #3000 grit discs or paper.


What are you using for,

Tool
Pad
Product


#3000 is pretty easy to pull out. Click on the picture below and you'll see me removing #2000 grit sanding marks using,

Cordless FLEX Finisher - Note the name, it's for FINISHING no so much for correction work.
Foam cutting pad
BLACKFIRE One Step - an AIO

Point being, if I'm pulling #2000 grit with foam on a free spinning orbital and a cleaner/wax, we can help you to pull out #3000 grit on whatever it is you're working on.

Did you try to remove the sanding marks with a Chemical Guys compound? I bet any of the compounds available on Autogeek would handle that task with no problem.

What's wrong with CG compound?

Their products often don’t deliver the results one is looking for. Great marketing though.

Wet sand with a short round of 3000 again, then 5000 in several directions, then all you should need to do is med compound and then finish polish.

i have done quite a few paint jobs and wet sanding. i havent ever gone beyond 1500 grit. i used to use megs M105 and an orange lake country pad on a 7424. took some time but always worked.i dont use 105 anymore-switched to m100 which works even better.
3000 grit scratches arent much and should refine with a quality compound.

dry sanding shouldnt make a difference unless the paper was getting loaded up.
