Since it's been a while since I spray-painted the boxes, I wanted to duplicate it before I posted any kind of tutorial. Just in case it was some happy accident. Well I did it again this week and it really does work so my friends...here is my little tutorial!
Dip your brush into the glue and brush onto the metal. Make sure you cover it! Too little glue just means a little scraping at the end...not a big deal but not as fun either.
As soon as the glue is dry you can start spraying!
When the paint is almost dry (basically if it's just a tiny bit tacky) then you can start peeling. Yay!
99.9% came off super clean and pretty except for the small spots that maybe didn't have enough glue. I just used my exact-o knife to clean up any little specks that didn't come off when I was peeling.
Put the box back together and VOILA! You have a rockin' box in the color you wanted! Yay!
If you try it, let me know how it goes!
