Will this work on crease damage or only shallow dents?

This tool is designed for moderate dents and creases in wheel arch panels. Severe structural damage or deep creases may require conventional dent removal — test-fit the tool to your damage before committing.

Do I need to sand or prep the panel before using this?

Light cleaning is enough. If the panel has heavy debris or rust, wipe it down first. You don't need to sand or prime — this tool works on existing finish.

Can I use this on plastic fender flares or only metal panels?

This tool works on hard panel materials. Flexible plastic flares may not hold a shape correction — confirm your panel type matches the tool's working surface before purchasing.
