First time wet sanding

[vvmanoj]

Hi all,
I recently got my Palio boot repainted and its got some serious orange peel. I can actually feel the paint wavy. The paint shop will not touch as they dont want to mess with it....probably dont want to wet sand.
I have decided to take the plunge and wet sand. Now what grit paper should I use? I was looking at the 2000 followed by the 3000. Here is an image



Also can I just use GC Shampoo when I soak my papers and lubrication or do I need #00
I was then thinking of following it up with some #80 on a g100 Will this be ok?
Thanks,
Manoj

It usually takes a rotary with a cutting pad to completely remove the sanding marks. The G-100 doesn't produce enough cutting action to completely remove the sanding marks

Thanks for posting that David, I tried several times earlier this morning to reply to this thread but my connection kept hanging-up?

David's right, unless the clear coat finish on your car is very soft and/or very workable, in most cases in order to effectively remove your sanding marks you're going to need the power suppled by the direct drive action of a rotary buffer.

If you've never wet-sanded and then followed-up with cutting out your sanding marks using a rotary buffer and a compound, then it's usually not a good idea to learn on something that's important to you, like your freshly painted car.

At a minimum you're going to want to do a Test Spot to dial in a process that you can then duplicate all over the entire car.

Might want to hold off on your order to ADS until you've taken some time to think this through.

Thanks for the input guys. I understand that the PC will not be able to remove the sanding marks completly...but I really do want to give it a shot.
I still have plenty of paint left, so repainting(if things go horribly wrong) is an option.Besides I will only be doing it on the boot.
So is 2000 followed by 3000 ok? And what would be a good compound/polish?
Thanks

You're best bet is going to finish sand everything with #3000 grit paper, probably cut with #1500, then chase this with #2000 and the follow this with #3000.

After that I'm not sure not what to tell you as Meguiar's doesn't recommend using our compounds with the dual action polisher at this time.

Also, the large size of the 6.5" foam cutting pads, i.e. this much surface area tends to bog down the rotating action of the dual action polisher, which is where your grunt work would come from if the pad continued to rotate, however with all factors included it will tend to more or less jiggle at a high speed, not very effective for removing sanding marks thus our recommendation to use a rotary buffer.

One option would be to seek out a smaller backing plate and a smaller polishing and even a cutting pad for the dual action polisher. The reduced surface area will reduce drag or bog-down on the rotating and oscillating action of the motor in the G100 and possibly give you more cutting power. This is all more or less hypothetical of course because as a rule we don't recommend using the dual action polisher for removing sanding marks so we don't have procedures, nor the tools for doing this.

I would suggest reading this thread all the way through... it makes some very good points...

Then see what others post for recommendations. One problem that many run into when trying to make the dual action polisher do more than it was ever intended to do is you are often times able to remove the defects you're trying to remove, but the finish you leave behind is dull and/or hazy. Using the same products and pads on the rotary buffer would have resulted in a high gloss shine, it all has to do with the action of the tool.

Easier to show than to describe using a keyboard.

hey man you want to be carefull when color sanding your paint job. use a soft foam pad to color sand and check every few swipes to see how fast it cuts. it seems that who ever painted the car only put 1-3 coats of clear. they seem dry and uneven, but it looks like maybe 2 coats maybe. watch for your edges they burn through much faster and easier. since it looks like a bright color 2000 will buff out with no problem, but 2000 grit does not take orange peel off. 1000-1200 does a better job at makeing a flat and reflective surface, but you need atleast 4-5 coats of clear to work with.
