Product review/Show and shine. 3M new 8000grit VS a Lincoln Mark LT

[Justins00ss]

So I recently purchased the new 3M 8000 grit Trizact disks in 6in and 3in. The purpose of these is to leave a surface that is ready to be polished without the need for heavy compounding.


How I see the benefits is that the 8000 is strong enough to level moderate defects(swirls etc) while still being gentle on the clear coat. For instance taking a heavy cutting compound and a wool or microfiber pad and making several passes while introducing heat into the paint.


I just so happened to have a Lincoln Mark LT in the shop that has had paint work prior so the thickness reading were on the high side. 9mil +/-. The paint had swirls, chemical staining from a car wash and other things. This was the perfect time to try this out.


Now 3M does have a one step polish and foam pad for this system. I did try the polish on my DA with some of my different pads and it just didn`t seem to work well. Granted this product is meant more for a rotary application so I will try it with my PE-14 when I have some time.









One downside is the cost of these disks are a little high. a 15pk of the 6in was about 107$. A 15pk of the 3in is around 50$ But they don`t wear out fast. I used 3 6in disks and 2 or 3 of the 3in disks. That is sanding everything but the front bumper and roof. I even sanded the huge fiberglass bed cover. But the trade off is time saved. I sanded and one stepped this truck in roughly 5hrs without the fatigue of heavy compounding etc.




For sanding I used my Rupes Duetto on speed 2.5/3 with a foam interface pad. I also used my 12mm swirl killer mini with a foam interface pad for tight areas. These disks are for damp sanding. Not to be confused with wet sanding. Just a couple mists of water is all that is needed.

Sanded with 8000 Trizact. Now you can see it leaves a almost transparent finish.







For polishing I used my Boss G21, Mckees Redline orange pad and 3D ONE. Now this worked perfectly to polish in one step. On some paints this may or may not work. Just need to find the right combo for what your working on.









Here is the hood. Notice the chemical staining.












All finished and coated

I love Trizact 5000 for headlights...this 8000 sounds really intriguing for paint. Thanks for sharing.

I agree wholeheartedly! Wow, 3M has sure upped their game in this area compared to back when, uhm...their papers weren`t so great.

Thanks for posting about this offering, sounds even better than 4K and that was a real improvement over the harsher stuff.

Oh, and I guess I`m not all *that* surprised that their polish might not be All That. There`s one area where they could still make some improvements, or borrow from corporate-cousin Meguiar`s or something.

Thanks bud. Yeah I thought the same thing about the polish. I had a feeling it would be sub par but I`ll mess with it some more.

Truck looks great. Interesting product for sure. I guess when you consider the time savings the cost definitely isn’t out of line.

Great review. I haven’t seen the 8000 grit discs. They would really be a time saver and paint saver. I’ve mainly used the Trizact papers for headlights, I’ll have to give them a try on paint.
