FAQs

What is the best way to store the sandpaper?

Store the sandpaper in a dry place to prevent it from absorbing moisture, which can reduce its effectiveness.

Can I use this sandpaper on plastic?

Yes, the Amtech S3865 sandpaper is suitable for use on plastic. Use appropriate sanding techniques and pressure.

What grit should I start with for car bodywork?

For car bodywork, start with P400 grit to remove imperfections. Then move to P800 and P1000 for a smooth finish.

Can I reuse the sandpaper?

Yes, you can reuse the sandpaper. Clean it after each use to remove debris and extend its life.

What is the difference between wet and dry sanding?

Wet sanding uses water or a lubricant to reduce heat and clogging, resulting in a finer finish. Dry sanding is suitable when water is not desired or practical.

What is the size of each sandpaper sheet?

Each sandpaper sheet measures 280 x 230mm.

Troubleshooting

Sandpaper clogs quickly during use.

Use more water or mineral oil. Reduce sanding pressure. Consider a coarser grit for initial sanding if dealing with heavy material removal.

Sanding marks not disappearing.

Ensure you are using the correct grit progression. Apply even pressure and consider using a sanding block to keep the surface flat.
