Just for learning: The local aerosol disaster that the proud amateur aerosol enthusiast was confronted with.
The panels were sprayed with spray cans from the rich offer of the Action. True for nothing but praise. The preparation was done with primer. Painting with .... Well: paint.
After spraying, the proud hobbyist thought that spraying is actually just a breeze ...
The following morning the sunny yellow varnish layer to have split into a kind of ice floes.
The substrate, the primer and the top layer apparently had a serious fight during the night. And that is because paint systems simply have to be coordinated.
The fact that the painter later found the result of his work quite beautiful, as in 'artistic'? That of course was a weakness.
You have been warned: sometimes craftsmanship is simply more important than goodwill.
And if you are going to spray, first do it on a test piece.
