Thanks Jim. I misunderstood the video. I thought they were saying only sand with 8000 and no coarser grits. I should have read further.Your not removing anything with the 8000. Its only for refining 2500-3000 or finer scratches.

Yes once I read the chart I knew I misunderstood the video. The video shows the 8000 removing a lot of material. Old age can be cruel sometimes…Im not seeing that. Chart says start with 1500 then 3000 then 8000. 8000 for micro scratch refinement
I'm using the 3M Trizact system now.Yes once I read the chart I knew I misunderstood the video. Old age can be cruel sometimes…

I used to use those exact compounds. Then I switched to 3D aca , and menzerna and sonax. Threw away all my 3M stuff....try itI'm using the 3M Trizact system now.
I use a hand block, 600 for runs, 1000 for peel, then 1500, 3000, 8000 Trizact, then 3M 36060 cutting compound, then 3M 06094 machine polish, then 3M 06068 ultrafine machine polish. Finally 3M 05990 hand glaze.
Works pretty good.
Yeah, I've made detailed notes from this thread and have a new plan for the current project. Hoping to paint right after July 4th and after 1-2 weeks curing, hit it with the new stuff.I used to use those exact compounds. Then I switched to 3D aca , and menzerna and sonax.

Yeah buddy. I put those products to the test my first go around on a black job I did. Results were great. I use a dewalt rotary to buff.Yeah, I've made detailed notes from this thread and have a new plan for the current project.

Black, arghhh . . .
Probably not sanding enough. Though I'm sure junk is getting under the paper and causing scratches. YES, large pigtails deep into the clear. I had to go back to 1000 by hand to get out the pigtails.i can tell you your not sanding enough with 1500 to get the 1000 out. that is #1. #2 the pigtails. when your dry sanding with the yellow discs are you seeing pigtails in the dust when you sand or are you actually getting random large pigtails in the the clear when your try to buff?
Using a Festool sander on speed 2 (of 6). Only using the weight of the sander, no pressure.many pigtail problems are from building heat and melting the sanding dust into small pebbles that stick to your pad and cause the pigtail . too much speed , too much pressure , too much heat .
Disclaimer, I'm no professional, but everything I paint I need to polish because I live in the middle rice fields and there's always wind and stuff in the air. Here is my advice. Never mix paper in a bucket. . Don't even bucket sand. Use a spray bottle. Only use microfiber towels, and or blue shop towels to wipe. Listen to what is going on. If u hear high pitch squeek...u got something between paper and panel.Probably not sanding enough. Though I'm sure junk is getting under the paper and causing scratches.

Here's 8 hours of sanding on a door today.... All by hand. 1000/1200/1500/2000. Trizact 3000/5000/8000. Cutmax, then ex 04-06. Looks great from 2 feet. Up close in the sun, scratches... 30 minutes after polish, pulled it outside, and already covered in dirt and dust. I swear this thing is magnetic. I'm almost embarrassed to show these pics.
The sideways scratch is from 1500. The vertical swirls if from the buffer.
