40-grit - More serious paint removals and heavy rust removal (not galvanized). Toothpaste marks on painted walls. Sand through any existing texture coatings (orange peel effect) without raising the grain. Remove but not replace wallpaper border designs. Moderate sanding of hardwood floors between finish coats or stain coats; removes marks left by 80-or 120-grit sanding (light color woods only).
Finish With 100 Grit - Lightly sand for a smooth surface before applying final coatings of paint or varnish; leaves no scratches.

11. What Grit Sandpaper To Remove Clear Coat?
My recommendation would be 60 or 80 grit sandpaper. Begin with the sandpaper of 100grit, which is usually coarser. However, if you sand for a long period, it causes the clear coat to melt and flow onto the paint layer below. So immediately move to either 40 or 80 grit paper until all traces of clear coat are gone.
It's important not to use too much pressure because this will remove some paint and a non-worn clear coat. The final step is to go over an area with lower grit sandpaper to confirm that all the old clear coat has been removed. However, this will require more physical effort than before since there is less surface contact between high and low grit paper due to the reduced thickness of the clear coat.
Three areas need to be sanded. First, you'll have to sand the scratches out using 60 grit paper with slight pressure on an angle that is not 45 degrees or 90 degrees but somewhere between these two angles. Then use 40grit paper and sand perpendicularly until both layers of scratches are removed.
And finally, use 100grit sandpaper to ensure that the scratches are gone and then go over it with your hand, ensuring that there aren't any scratch marks left behind.
The second important thing is not to sand on a very humid or rainy day because chances are you'll be removing some of the paint in addition to the clear coat, and this will eventually lead to permanent damage in addition to a reduced resale value. Also, wear goggles and gloves using rubber sheets on your arms so that no part of your body touches the car. If you do so, there's a high possibility that you'll get scratches or even injure yourself, which would be very unfortunate.
