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.
Can I apply sealants or waxes with it?
Whilst a fine cut finishing pad would be the choice for sealant or wax application, there is little value in applying waxes or sealants by machine - you need coverage not cut - so just apply them by hand using a foam finger mitt (WaxApp) applicator.
Is it suitable for DA machines as well as rotaries?
Yes, Peak Finish waffle pads are ideal for DA polishers and rotaries. All machines that have the correct style and size backing plates, in fact.
Will it cut at all?
It can do with the right polish combination and polishing techniques on softer paints, but there are better pads available for cutting... Peak Finish is really for finishing.
Why the waffle design to the pad face?
Waffle pads tend to run cooler in operation, allow a better spread of polish across the pad face and even prevent polish splatter or 'sling'. The differences aren't vast but people do like waffle pads for a reason. Sometimes it comes down to what simply feels right. The waffle design is a bit of a classic that has stood the test of time and remains popular to this day; it is just as revered by enthusiasts as relied on by bodyshop pros.
