When I first started using aerosol paints, the number of mistakes I made was almost laughable, but they taught me valuable lessons. A big mistake is not preparing the surface properly—whether it’s not sanding or failing to use a primer suited for the material. Trust me, skipping prep steps only hurts in the long run, as the paint won't adhere properly and will chip easily. Another common error is spraying too close to the surface, which often results in drips. My rule of thumb is to keep a distance of about 10-12 inches and always apply in light, even coats. If you're new to this, practice on scrap material before tackling your main project. As I was looking into it, I found a useful page that could be worth your time. Anyway, patience is key—rushing through drying times between coats can ruin an otherwise perfect finish.
