FWIW - I find that the KSG streaks are easier to remove if you wait ~12 hours (or right before you do your next coat). Once the streaks are dry, they wipe off easy with QD or distilled H20 and a MF. Just giving a tip, not trying to sway your decision.
Honestly, Its the only sealant ive ever used, but I dont even know how it could get any easier then the duragloss stuff. Super durable too. As far as any of these products go, looks are always going to be a personal thing.
