it needs to be revolving polisher
wash mop, and constantly spray the surface. use a garden pump-sprayer to get a fine mist.
always spray surface and spray cloth. polished needs to be wet to work.
let it use its own weight. put the polish on the part then the polisher on the dollop. then push polish all over the part. use pump sprayer a lot.
with carbon fibre, always wet sand, then if the water goes grey, you’re through. this is not a good thing.
