What paint to use on power outlets

I would use Krylon Fusion or Rustoleum for plastic. they both should bond to the recepticles.

I guess your wife objects to the color of that little area that would otherwise be covered with a plug. If thats the case perhaps you can fill it with those little plastic childproof caps. That is if you can still find them. They were reputed to be of very little deterent to prying fingers and a choking hazard as well. Needless to say my recommendation is DON'T USE CHILDPROOF OUTLET CAPS WHEN CHILDREN ARE AT LARGE. The same warning may hold true for pets.

Jax,

In my experience the MD Audio Paint causes smearing. I've found the UltraSilvaPlatClearKote with organic dye colorant and baking-soda opaquing agent (available via special order only) is completely transparent and adds bass. The SlivaPlat coating is very pricey, but it's well worth it.

exhange them for another color

Nsgarch and Rwwear are correct about the paint types - unless you get a paint for plastic (or sand the plate to remove the gloss) regular paint will just peel off glossy plastic.
