Frequently asked questions

Which pad should I use with H9.02?
Ideally, use a Heavy Cut Pad – a hard foam pad designed specifically for this compound.

How do I wipe off excess compound after polishing?
A clean NOX FiberWipe microfiber cloth is all you need. For an extra-gentle final wipe without risking new marks, NOX FiberBOA is also a great choice.

It is the same compound with the same formula – the 1 L package is more economical for frequent polishing or professional use.

Use Micro Cut M3.02, which removes any holograms and adds a final gloss.
