I had quite a bit of scratches and a tad bit of dust on my hood and wanted to fix that. I've spray painted cars before but only small areas, nothing as large as the hood. Sanded the affected areas, applied 3 strong coats of primer and gave it around 3 coats of spray paint. Unfortunately, this happened. This image was taken approximately one hour after painting.
This is my second time attempting this. No matter what I do, I always have these marks...what am I doing wrong? What do I need to do to fix this? :(
