Do I need a different backing plate with spot pads?
You will need a smaller 75-90mm backing plate to use with these smaller spot pads. Check that you have one with your machine, or buy one specifically. Remember orbitals and rotaries use different backing plates - one won't tend to fit the other.
Will it remove swirls?
Yes, of course, assuming the right polish combination and polishing techniques on soft and medium paints, but if you need more cut consider Fibre Scyther (DA) or Slim Reaper (rotary).
Is it suitable for DA machines as well as rotaries?
Yes, Shark Fin pads are ideal for DA polishers and rotaries. All machines that have the correct style and size backing plates, in fact.
Why the fin design to the pad face?
Fin pads tend to run cooler in operation, allow a better spread of polish across the pad face and even prevent polish splatter or 'sling'. They can sometimes feel a bit more consistent in use and allow for a more forgiving polishing angle (between pad face and paint surface) than flat pads. Like the popular waffle pad design, but just a bit more extreme in execution. We think you'll like it.
Will it work on headlights?
Yes, it’s small and precise enough. You may need to flat the headlight lens first with the correct grade sanding paper (advanced technique!) or use a different pad or polishing compound so be careful when you work on headlights.
