problem with Diolen look

hi guys,
i'd like to ask you if somebody has some experience with Diolen and with his look after coating.
After applying of top coat I am observing an unequal pattern or texture on surface from Diolen. Diolen fabrics itself looks good but after applying of top coat some strings of fibre
are darker than others. The more top coats the worst effect.
steps in skinning:
- black base coat then diolen
- 1st layer of top coat >>> images 1st layer.jpg
- 2nd layer of top coat + Lacquer >>> images 2nd layer

on pictures are different parts of skinned parts.
when I used only 1st layer of top coat the lines are visible but not so much.
after applying of 2nd layer the "lines" are visible too much.

Could it be a faulty Diolen product?
I tried to apply top coat with brush and also with plastic card but still with the same effect.

any help or advice is more than appreciated.
thank you very much

I've had a look and seems I used the last of the fabric but I do have part of the original sheet where you can see the lines. I can send this if wanted, but like I said, I doesn't really bother me, it would only be if you guys wanted to check it. I was purchased mid summer last year so chances are you onto a new batch by now anyway
