Yes, you can polish out 1200-grit scratches, but it is highly aggressive. Attempting to jump straight from 1200-grit to a final polish will result in a hazy, dull finish. To achieve a flawless, mirror-like surface, you must incrementally refine the scratches.
Grit finishing paper is referred to by the size of its abrasives (i.e. 1500-grit paper) the grit you use depends on what kind of scratch you are trying to remove Compound: 1000-1200 grit Polish: 1500 – 2000 grit Finishing polish: 2000 – 400 grit Materials used - most good compounds are a combination of both silica and ...
1200-grit sandpaper is an ultra-fine, micro-grit abrasive used for final polishing, buffing, and eliminating microscopic scratches. It is rarely used for shaping or stripping materials. Instead, it is the paper you use at the very end of a project to achieve a glass-smooth texture.
Yes, you can buff out 1500-grit scratches. To do it safely and effectively, you will need to use an aggressive heavy-cut compound paired with either a microfiber or wool pad on a machine polisher.
Yes, clear coat will stick to 1000-grit, but it is generally considered the absolute maximum limit for fine-grit preparation. Because 1000-grit is very smooth, it relies heavily on chemical adhesion rather than mechanical "tooth," meaning there is a higher risk of peeling over time.
Always progress through finer grits (1500, 2000, 3000) to remove previous scratches while minimizing clear coat removal.
WD-40 doesn't actually repair scratches, but it is excellent at temporarily hiding very light surface marks and removing paint transfers (like when another car scrapes yours). It works by acting as a lubricant and temporarily filling in the scratch or dissolving the foreign paint.
Best Grit Sequence for Scratch Removal
1500 grit: Refines sanding marks from 1000 grit. 2000 grit: Smooths the surface for polishing. 3000 grit: Leaves a near-polished finish, ready for buffing.
If you plan on adding more coats of clear, don't bother to polish, just wet sand them with a fine grit. But be careful. With only two coats of clear, it will be really easy to sand through and ruin the color coat.
1200 Fine grit abrasive discs are electrostatically coated. This causes the SiC particles to stand on end, which provides more of a “cutting” action. 1200 Fine grit is recommended for soft materials that smear, step grinding for failure analysis, or when continued material removal is desired (typically after 600 grit).
Choosing the Best Grit for Sharpening Knives
For most home cooks, a 1000-grit stone is the best option to get started. Follow up with a 4000 or 6000 grit stone to polish the edge. An 8000 grit is very effective for those who want an exceptionally refined mirror finish.
Why Use Grit 1200 for Glass? Fine Abrasive: Gently removes scratches without damaging the glass. Perfect for Polishing: Prepares the surface for a smooth finish.
Polishing typically requires ultra-fine grits ranging from 800 to 3000+ to achieve a high-gloss, mirror-like finish. The process involves a progression, starting with fine grits (600–800) to remove scratches, then moving to ultra-fine grits (1000–3000) for polishing, and finally using polishing compounds for the final shine.
If you start with 1200 you need to work your way to 2000 and even up too 3000. If you use some 105 on 2500 or 2000 you will get the sanding marks out.
The Top 8 Metal Polishing Mistakes
Use coarse sandpaper of 24- to 40-grit to remove old paint, 150-grit to smooth out the scratches, 240- to 400-grit for wet sanding primer and 1,500- to 4,000-grit for smooth finishing.
Black and other dark-colored cars are widely considered the hardest to keep clean, and there's a reason for that perception. Dust, pollen, water spots, soap residue, and light scratches are all, for the most part, light-colored contaminants.
For a deep scratch that goes past the clear coat and into the primer or metal, pastes and waxes won't work. You need a touch-up paint pen or automotive glazing putty to fill the gouge. Applying these materials restores the paint's color and protects the metal from rust.
Yes, a Magic Eraser can "remove" certain types of scratches, but it does so by acting like extremely fine sandpaper. It is essentially grinding down the top microscopic layer of the surface to buff the scratch out.
While WD-40 is a great multipurpose solvent, it is a poor long-term lubricant and should never be used on items that require specialized lubricants, come into contact with food, or are made of sensitive plastics and rubber.
Deep scratches that expose bare metal or primer cannot be fixed with simple polishing. You need to physically fill the groove and blend the surface. To repair deep paint damage at home, you will need a touch-up paint kit (with color-matched paint and clear coat), fine-grit sandpaper (2000 to 3000-grit), a rubber squeegee, and polishing compound.
Apply 2-3 coats waiting 10 minutes between coats. Recoat within 2 hours or after 48 hours Dries in 30 minutes, handle within 2 hours. Wet-sanding and buffing is not required.
It is typically safe to apply a second coat after four hours for latex paint and 24 hours for oil-based paint. Latex paint is dry to the touch in about one hour, while oil-based paint is dry to the touch in about six to eight hours.
