Resolene peeling off... What am I doing wrong?

[porfido]

Hi all!

First of all, please, forgive my bad english, but I'm writing from Italy...

I wanted to ask you some advice:

I used two times resolene (50% in distilled water) airbrushing it on two dog collars that I dyed with Fenice Waterstain 

Maybe is it the same as Tandy Waterstain?

Anyway, after airbrushing Resolene in many light coats and letting it dry one or two days, lightly scratching the surface with my nail it comes away...

The "semigloss" finish comes away very easily...

Could it be the "waxy" effect of this waterstain to block resolene from penetrating and fixing?

I really don't understand...

Thank you for the answers!

It's really weird...

Resolene peels off also on only oiled leather...

I really can't understand...

1- make sure your air pressure is not too high 12-16 psi

2- are you letting your leather dry after your last application?

I would bet you drying it out before hitting  the leather with too high of air pressure.
