We can sweep and sweep and sweep and the dog hair just floats everywhere. We find it on top of the door jambs even. Frustrating that it ruined your door.
I hadn't thought of using more than one coat of the clear coat. I'll have to give it a shot and see if doing so will brighten things up for my one door. I'd really like for the colors to pop more.
One layer is still pretty susceptible to scratches and dings. My mini door is thick enough that it looks curved in profile haha! I like it that way though. Just takes forever to cure. When you layer it on that thick you either need the willpower to not use it for a few days, or you need to bake it to cure it faster.
Of course you have to be really serious about keeping it at that point. That much clear coat will take forever to get off with a scotch bright pad. You'll likely need to actually sand it.
