Painting steel cream cans
I have steel brushed and cleaned old cream cans. Next I sprayed the cans with spray paint. I want to paint with acrylic paints on the cans. Do I have to prepare the sprayed paint area with a paint that that will adhere to both enamel and acrylic (if so which is the best paint to use?),or should I give it a lightsanding and wash with TSP, so that I can paint acrylics on them. I will be painting sunflowers ,a deer, and welcome on these cans. They will be indoors.
I’ve included a picture of the type of project I’m interested in.
