Wet sanding

[xrmte]

When using the Meguiar's 2000 grit paper with

sanding backing pad (wet sending by hand)

Is it better to wetsand in a straight forward and backwards motion if not what is the correct way of doing this?

And what compound to buff out will m105 be fine?

Watch this one carefully. Maybe it will help.

Welcome to Meguiar's Online. M105 Ultra Cut Compound will remove up to 1200 grit sanding marks when used with a rotary polisher machine and the appropriate pad. So yes, M105 is perfectly suitable for buffing out sanding marks. In fact, M105 is our most premium cutting & finishing compound we produce.

In regards to hand sanding technique, instead of me writing a huge long response, check out the below thread. There is detailed information on hand sanding techniques, DA Sanding Techniques, and Rotary Polishing Techniques w/ video:

Hope this helps.

So i had a panel resprayed and on closer inspection can see a few dirt nibs and minor paint imperfections.
Maybe orange peel?

Should i wed sand the whole area or just the nibs and imperfections?

I certainly don't qualify to answer this so take it with a grain of salt but:
Depends entirely on what you are shooting for.

If you want a showcase finish, you'll have to wet sand the whole car (the quality of reflections on the pictures seems to show orange peel about everywhere, which would be expected).
If you are aiming to fix the most annoying imperfections only, restrict your work to 2x2s areas around them so that they blend nicely.

Yes i would like to fix the imperfections that are in various places of the car and have an overall shine on the entire car.

So could either use a trizac 3m disc or a megulars disc i take it there's not much difference between the two?

Once again, I'm thoroughly NOT qualified to answer any of this. I'm just a week-end warrior that did a lot of research.
Hopefully, someone with actual experience will take pity on you and answer your questions more definitely than I can.

If you want my two-cents tho, I'd say 3M cutting disks will be required for levelling and Unigrit 3k foam-interfaced for refining/matching.

Jason Rose goes over the essential difference between the two types of sanding disks in this video.



Good luck.
