P80, 150, 180, 240: skip one and the scratches stay #Shorts
P80, then 150, 180, 240. Skip one, and the next grit can't take out the last one's scratches. A plastic bumper? A red scuff pad by hand, never coarse paper, then plastic prep and adhesion promoter. Clear coat? All wet: P1200 only on runs, then 1500 and 2000, up to 5000 before you polish. The free Grit Selector gives the order for your job and your surface; the whole tool is the full video on this channel. Next up: the Mixing Calculator. Follow so you don't miss it.
The booth, the driveway and the scratch close-ups are AI-generated video and the narrator is an AI voice, labelled on screen. The tool on screen is the live Grit Selector on our store, and the shop at the end is ours in South San Francisco.

P80 to P240 P80. Then 150. 180. 240. Skip one, and the next grit can't take out the last one's scratches.
Scratch by scratch P80 leaves deep scratches. Each finer grit takes out the last one's, until primer can cover them.
A plastic bumper A plastic bumper? A red scuff pad, by hand: coarse paper tears it. Then plastic prep, and adhesion promoter.
Clear coat After the clear, it's all wet: P1200 only on runs, then 1500 and 2000. To polish, up to 5000.
Next up The job in, every grit out, free at autofxmart.com. Next up: the Mixing Calculator. Follow so you don't miss it.
