Gtechniq P1 Nanocomposite Polish
P1 is a very different kind of polish. Breakthroughs in nano-structured composite materials allowed us to develop an incredibly uniform abrasive particle on the nanoscopic scale. This allows us to manufacture a polish that requires almost no lubrication, which offers three important advantages.
The first is speed / effort. With many more active particles working the surface, the polish works faster with less effort than traditional compound abrasives.
Secondly with virtually no lubricant, a P1 finish doesn't suffer "drop back". This is where the lubricants in a traditional polish hide minor imperfections, typically micro scratches in the polished surface, only for them to be revealed after the lubricants have washed off. With P1 what you see is what you get.
Finally, temperature. Or to be more precise, the lack of it. Smaller active particle size means the surface doesn't heat up nearly as much as with conventional abrasives. This means much less likelihood of burning through paint and it also means you can make several passes over the same area to remove stubborn scratches, without fear of over polishing.
