How to remove 2000 grit sanding marks completely?

**zckid** · 02-25-2012, 01:35 PM

Hello everyone!

I've read a few threads on wetsanding. Got some tips from it.

As the title says, How would you completely remove 2000 grit marks if this were the finest grit you had?

I'm using the rotary and LC CCS orange pad with Menz PG (the old one).

I must say that I'm having a hard time knocking the 2000 sanding marks with the orange pad. (maximum speed 3) btw, the 4' inch pad seems to do a better job than the 6.5 pad correcting scratch and sanding marks even if it doesn't completely remove them.

The finest grit here I can get is 2500 (mirka). it'll be in a few days though.

Do I need to increase the speed?

would the LC wool polishing pad be a better option at getting rid of the sanding marks?

Also, how long can you use a sanding paper?

looking forward to hear from you.

Many thanks.

Zaid

I've been successful using 3m rubbing compound with a rotary and a wool pad followed by 3m machine polish and a Meguiars yellow foam pad....

Agree.

As for the sandpaper, you use it till it doesn't sand as well. You can tell when you grab a new piece and it "grips" a lot better then the old one. Basically you will feel the old piece not scratching and just sliding along the service.

Rotary and a wool pad.

I never had any problem using DA+orange pads+M105 to remove 2000 sanding marks, as long as using light and even pressure when sanding.

On soft one-step or CC, I can even remove 2000 with hand applicator and M105

Just my 0.02

Wool pad on a rotary buffer and a good compound.

What I always say and type goes like this,

Sanding is the easy part, that's putting scratches into the paint... the tricky part is getting them out...

If it's a re-paint and the paint has dried and hardened then getting them out is the tricky part.

If it's factory paint then getting the sanding marks out will also be tricky as you don't have a lot of film build to work with and you don't want to get a panel to hot as you're buffing.

Read these articles from my article list if you haven't already...

Wet-sanding - Fresh Paint vs Factory Paint

Fight or Flight Method for Gaging Surface Temperature

How long will a half sheet of wet/dry sandpaper last before it stops cutting and you need to replace it?

There's a slight difference between everyone's criteria for a good job.

My goal is always 100% removal of all sanding marks, whether they be tracers or pigtails. Most wetsand jobs I've inspected have sanding marks left behind, that is the sanding marks were not 100% removed.

Removing 100% can be difficult, it helps to have plenty of paint on the car to start with. Lighter colors can make it more difficult to see if you did in fact remove all the sanding marks, so look at the paint at an angle and/or in different light settings.
