Taped seams on mine are five years old. I don't think they are attractive, but I have an older RV that needs the protection and it seems to be working as intended.
I have photos from when I first did the taping.
And here is a close up from a photo this summer.
I used two layers of 2" eternabond to cover the corners. That double lapped the actual seam and was easier to apply than a single 4" piece. I also replaced the trim screws with stainless screws. Kept the old trim insert piece though.
This summer I bought more tape and new insert to do the front seams. The plastic insert is starting to sag at the corners and figured I should do the front seams but I have not gotten to the project yet.
This should give you an idea of the outcome though.
