Choose car buffers and polishers by how the pad moves and the correction you need. A rotary tool spins continuously and calls for careful heat and edge control. A random-orbit tool can suit polishing or wax application when the pad, paint and product allow it.

Choose by the paint and the required motion
- Check whether the finish permits polishing. Matte, thin, failed or freshly refinished coatings can require a different approach.
- Match the mounting thread, plate and pad diameter and speed rating. Keep cutting, polishing and finishing pads separate.
- Choose the least aggressive combination that may address the defect and follow the product instructions.

Work a test spot before the whole panel

- Install a clean compatible pad with power disconnected. Keep it moving on the panel as directed and check heat and residue.
- Inspect the result before adding more cut. Stop for damaged coating, unexpected color transfer or uneven finish.

Frequently asked questions
Does a higher RPM number mean a better finish?
A rotary speed and an orbital speed measure different motion. Choose the machine, pad and setting for the paint and job.
Can a random-orbit polisher damage paint?
Incorrect pad, pressure, speed or time can still damage a finish. Start with an approved mild combination on a test spot.
Do all three use the same pads?
Check the plate, pad diameter, mount and speed rating for each model. Use the accessories the maker allows.
Should I use a machine for wax?
Check the wax and paint instructions. Hand application can suit some jobs, while approved machines and pads can spread suitable waxes.
