Let me tell you, these SPTA wool pads have completely transformed my car detailing routine. The first time I used the purple heavy-cut pad on some stubborn oxidation, it cut through like butter - no jumping, no excessive heat, just smooth, controlled polishing.

What really surprised me is how the different colors actually perform differently in practice. The beige medium pad became my go-to for removing light scratches, while the orange light-cut pad gives that perfect final finish. They're so much more aggressive than foam pads but somehow gentler on the paint.

After polishing three cars back-to-back (yes, I got carried away), I can confirm they don't shed like cheaper wool pads. The Velcro backing held strong through all sessions - though I did notice some minor deterioration after heavy compound use.

Pro tip from experience: these do load up with compound faster than expected. I keep a stiff brush handy to clean them between panels. And yes, they will slow down weaker buffers - my old rotary groaned a bit until I upgraded.

The real test came when I tackled my neighbor's boat hull with years of oxidation. These pads cut through it all while leaving enough wool fibers intact for multiple uses. Just machine wash them gently and they're ready for another round.

For professional results at a hobbyist price, these are absolutely worth every penny. They've earned a permanent spot in my detailing arsenal.
