I actually did a belt buckle refashion a while back with nail polish but I thought I’d try spray paint this time.
This ended up working really well! I made sure to cover up the belt before painting with masking tape. I then did two coats on both sides of the buckle and left it to dry overnight. The next day I painted a gloss finish on top with clear nail polish (this wouldn’t be necessary but it definitely improved the finish and I imagine it will help the paint stay longer too). I also used some black nail polish to paint the stud (I used a toothpick to paint right down into the sides).
I really like how this belt looks with a black buckle. This finish is so much nicer than the one I did with nail polish too. Yay! Hopefully I’ll get lots of wear out of this now.
