I've got some boxes I want to use for swarm traps that have been painted with (white) exterior acrylic latex. I'm not sure of the type (it's sitting at work right now) of spray paint I picked up to camouflage the boxes but it's the less than $4 kind from Lowes. I figure it's an enamel of sorts. Will this work over the latex? I'm not looking for showcase quality....just something that won't peel for a couple of years.
