Worked great on glass lightbulbs and steel wire! I came across this DIY Halloween project to make these cool spiders made from old lightbulbs and wire, and thought, I can make those! So after cutting the wire into 4 equal lengths, I bent them around a lightbulb to make the legs. Then I used a bit of glue around the neck of the spider to hold them all in place. Once they were all dry, I gave them 2 coats of this Krylon paint on both the top and bottom. Not once did my can leak or have any issues, and I had plenty to do probably another set of these spiders. Id like to,say you get a lot in these cans, but in reality, you dont. However, they are cheap enough, or at least it was at the time I purchased it. I chose this particular one since it was a paint and primer in one, because I didn't want to have to mess with multiple coats. I probably didn't even need to do 2 coats, but because there were so many nooks and crannies with these, I needed to in order to get the full 100% coverage. Overall, they came out perfect with a nice smooth finish on both the glass body and the wire legs.
