I use it for spot-treating scratches my normal PC routine doesn't get, and I like it. I use it by hand, one finger, foam pad. Wipe on/wipe off - it has reasonable filling capabilities and very nice gloss. rub hard, 2-3 applications - you can safely remove clearcoat.I usually stop when the edges of the scratch are rounded - rather than remove so much paint that the scratch is gone - I'd rather have the clearcoat and this effectively hides the scratch forever.
there are certainly more aggressive compounds - but this is aggressive enough that I feel I have good control over it by hand, and it leaves a very nice finish.
