To 3k sand or not

[DBAILEY]

You would end up with a smoother paint surface using the #3000 or #5000 first knocking down the orange peel texture a bit. Does the current condition of your paint really warrant wetsanding?

I get this, but Im wondering are there any major differences from sanding 3k versus long passes with a MF pad and say, m100.

After sanding with 3k you still need to polish and a lot of time this will require a 2 step polish.

Any time you can compound and polish to get the job done would be better than wet sanding.

Maybe the 5000k-8000k that Mike mentioned will be easier.

•Since none of my OEM vehicles have ever
been predetermined/destined to be entered
into any Custom Car Shows...

-I need my vehicles to retain as much of
the protective CC paint film layer as I can
Humanly {and possibly humanely} provide.


Consequently...
•When it comes to OEM factory paint systems:
-I don’t wet/dry sand them
-I don’t use anything more aggressive
than something along the line of Meguiar’s
Ultimate Compound


•With the above in mind, I’m compelled to ask:
-What’s the advantage to do otherwise?

It appears that the OP is talking about trashed paint. Wouldn't consider using a rotary with a wool pad and compound to smooth out orange peel. Maybe a denim pad and a da would work..dunno never used a denim pad.

Don't wetsand anything unless you have experience or at least some type of basic training. You can run into problems very quickly. Practice on a junk panel first before doing a customer car.

correct. paint that's trashed to where it would be faster to sand and polish out.

I have plenty of experience wetsanding and knowing when and when not to.

this is just a general question




This is more of a topic Im just asking about. I see a lot of detailers online and IG that go right to 3k handsanding on trashed paint because it allows them to keep their heat under control and not letting the paint swell.

Keeping temperatures low is better for the paint and one advantage to dampsanding over a heavy compound process.

To the OP if what your saying above is true, why are you posting this thread?

Is it because you have no experience with a rotary and a wool pad?

This was more towards the ones I see that go right to wetsand and compound to reduce heat into an extremely beat panel. Does it do more damage or not, basically. Guess I should've stated it totally different.

IMO if the paint is that trashed and a aggressive method needs to be used..put a paint gauge on it before anything else.

3000k versus rotary with a wool pad and compound would be a close race in removing clear coat.

BTW trying to remove RIDS with 3000k imo is wasting your time. If the panel is really trashed and has enough clear then start with 1000k and work up to 3000k.
