Estes Semi-Scale Saturn V, Kit #K-39, Part 22, Fixing The Black Paint

I visually centered the mask line between the fairings. 

But - two of the black edge ended up to the right of center.

I used an old trick - 

On the left, a fine point Sharpie was sued to draw a new border line.

On the right, the white area was filled in with a wider point Sharpie. 

Perfect? No. But, it beats re-masking and spraying again.  

Here's how the #7 wrap will fit between the fairings. It will require some trimming to fit into the fairing fillet area.

There is some slight yellow discoloration in the old print.

Note the mask line at fin slot area looks rough. There is still a strip of masking tape in the slot to keep out the paint.

Here the fin slot tape strips have been removed. 

That bit of black above the mid point mask will be covered by the #6 wrap.

The rough mask line around the fairing will be covered with silver paint.
