Shim Making. Return Edge?

[A Master Builder]

The Gaps in between the kidney and ABS, I have started to make my approach on making my shims. I have a sheet of ABS matching the color of my AP, I have the cutouts of the shims for both sides. 

 

The Question is, Do I create create a return edge on the shim to bend in?

 

I was going to hold my shim with velcro or for sale sign material, which one is better?

 

After putting it into place, Im going to make ABS paste, to cover the crease, then sand it, polish it with Novus.

I would glue a strip of ABS behind the join. You don't want that to move at all if you are going to hide the seam with ABS paste.

 

 

You could add a return at the top and bottom as that's the most visible. The butting edges of the actual an and kidney could be hidden.
