Wiped the areas to be primed with waterborne wax and grease remover and wiped with wax and silicone free tack cloth. Because of how cold it was outside and didn't think the garage could maintain above 65 degrees I decided to brush the epoxy primer. My test piece looked great so I figured it would turn out the same but I'm not happy with how it turned out. There is nothing wrong with the coverage just don't like it and it was harder than spraying. I had problems around the holes, primer liked to run. I learned I'll wait to spray the parts next time.
