I was in the process of fixing a crack in my bumper and repainting it. I fixed the crack (or thought so), and then repainted the whole bumper.

As I was moving the bumper from my backyard, to the front yard, it hit my gate and developed a slight crack right on the old crack. So I basically sanded that spot down, applied some more epoxy, sanded it down, taped it off, reprimed the spot, then repainted, then clear coated.

But when I took the tape off (i'm a noob), there was tape lines, it's very noticeable and looks like crap. I thought I could use one of those touch up pens, and kinda 'scrape' at the line or make it flush, and then use that small brush so that's what I did, and all that brush did was make a wider line that is above the surface now.

So what can I do? Can I just sand down that whole area again 'til it's even and just spray some dupli color, and then some clear coat? I used dupli color perfect match for the bumper.
