Awful decal. It is scattered in attempt it to translate. There are ideas as it to correct?

Ok. My work on models is slower than I want it to be :)
Opel is almost ready to varnishing.
So some progress for today:

Opel Admiral (ICM) in progress

I painted Opel in gloss black with a couple drops of gloss white. The result is satin like surface. After paint completly dries I masked areas near chrome parts, which would be painted next.

So, let's start.

Here is some photos in progress. The body is primed, the frame and the engine are painted, rust traces are put on the muffler. I decided to build this model out of box with minor of scratch build.
