What are the dangers of skipping primer when using oil based spray paint?
I haven’t ever had a problem skipping the primer with glass, metal, fiberglass, terra cotta, or plastic because of the oil based nature of spray paints mentioned above. My only real problems arise when I skip primer with glossy or wood surfaces. With wood or laminate, you risk the paint not sticking over time or the dreaded bubbling and cracking that can occur in certain conditions when the surface repels the paint. Which brings us to our next question.
