When I started my trade in ‘76 professionally.....the finest piece of sand paper was 600 grit. Lacquer was King ...and that’s what we sanded it with ...before buffing. Now it 8,000 grit........I’ll tell yah,it’s a lot less buffing...LOL

The Sunday funnies are coarser.

That 600 grit back then is roughly equal to 1200 P grade today. Just a difference of US vs European designation.
I’ll be using the 8000 in a few days, polish and done!

Did you get the whole system.....with the quick connect adapter that goes on the buffah .....for the 3M foam pads ? Pretty slick !

Since the days of the caveman man has tried to find a way of making life easier. One of those ways was to invent machines to do the grunt work. I prefer to let my polishing machine do the work. That is what they are in my toolbox for. I'll keep using 1500 and the 3M Perfect It system.

Who is moving the polisher back and forth while "it" does the work?

Yes, quick connect and foam pads. Nice system.

Chief,

If you used the Trizact system, you will spend less time with your polisher.
Either way, your still doing the work. You may be surprised, give it a try.

Just finished a Tri Color Pearl White on a Nissan... nose and blend the doors...de nib with 1000 wet by hand ...then the DA wet with 2000 .....then 3000....then 8000....then Just One pass with the rotary buffer....then switch over to the DA with micro fiber pad for a second pass to remove swirls......all done ! The Chief would still be buffing....

For those who have not tried the Trizact system on a DA, here is an important tip. All of us probably know what it feels like to be wet sanding and you pick up a some grit (or contamination) on the surface. You feel it rolling under the paper, and you know it's carving a path in your clear coat. You stop and flush the paper and the surface.
When using a DA, you have no sensation of that same feel while the pad is moving. IT IS CRITICAL that you keep a source of clean fresh water moving to flush the surface while machine sanding. Being sloppy about the surface or what contacts your paper will allow grit on the painted surface (or paper) and leave you with deep squiggly curly Q lines (scratches) in your clear coat. That can mean the difference between finishing the job and repainting because the curly Q's.

There are much better compounds than 3M perfectit. The 3M is full of fillers and will inevitably die back. Menzerna and Sonax are far superior in my experience.

“The 3M is full of fillers and will inevitably die back.”

I have no dog in the 3M fight. If you are seeing die back, with any product, you are not thoroughly refining the scratch. When the “Filler” is washed away, often in the detail bay, it exposes the underbuff.
A simple wipe with some alcohol will reveal exactly how well you’ve done.

That's why I don't have Mirror Glaze in my shop. All it does is fill the scratches from an incomplete buffing. Meguiar's 85 handles most jobs, and we also use rubbing alcohol and water in a spray bottle as a last cleaning step. 25% alcohol and 75% water will also dissolve dried compound residue in cracks and crevices that can make a buffing job look sloppy.

The products I mentioned don’t have the fillers and buff faster. They are just better in my experience.

Seems like a pass with 8000 is just replacing rubbing compound. Less mess I guess. What is the secret sauce after 8000, swirl mark remover?

One pass with this stuff,on the rotary buffer....followed by another pass of the same stuff on my orbital buffah....and done !

Ida Automotive just finished an early Porsche with 8000 then hand polished it. A few passes by hand and it was polished up.

I guess you could hand rub...if you were a scared of a buffer.

Or I guess you could use 8000... if you were a scared of a buffer.

Here’s a look at the Perfect-it 1 step system.
1500, 3000, 8000 then polish.
Need to spend a little more time with the 3000 refining the 1500 but really easy and much cleaner without all the compounds.

[jww]

Here’s my ?.........is 8000 used in place of say a wool pad and compound?
I guess this mounts on a d/a like 3000? I use my 3000 wet so same with 8000?
After 8000 do you go over it with foam pad and polishing compound to get swirls out?
Doing a black 57 Chevy right now. Wet sanded with 1500, 2000, 3000 and ready to buff with wool pad, then foam. What’s the steps using 8000?
Never knew this 8000 existed till this post, thanks a bunch!!!
