Interface Pads

An interface pad is a soft foam layer that fits between the backing plate and a sanding disc, so the disc follows curves and body lines instead of digging in at the edge. The range is the Rupes Soft Interface Pad, 125mm (5 inch) and 12mm thick, in a pack of two.

How to choose

Match the diameter to your backing plate and discs.

• 125mm, 12mm thick: for sanding a whole panel, for example levelling orange peel, with enough give to follow gentle curves.

Good to know

• The discs to go with them are in Wet Sanding Discs, including CarPro SIC and Rupes X-Cut discs in 125mm (5 inch).
• Check the disc sits centred and grips firmly before you start: a disc that slips or overhangs the foam can mark the paint.

What is an interface pad used for?

It sits between the backing plate and a sanding disc and adds a soft foam layer, so the disc follows curves and body lines instead of digging in at its edge. That gives a more even cut when wet sanding orange peel or a run. Match its diameter to your plate and discs. Our compound vs polish guide covers the polishing that follows.
