Girls that have made WE DO letters

When you painted them, did you use that stuff that makes them shiny? Shlack, sp?
Im using the regular wood ones, not the whites wood.
TIA

These were mine painted in 'Silver Anniversary' by Folk Art paint. I put on 3 coats and it had enough sheen I didn't have to use a gloss. I have used clear glossy spray paint for a finish on other projects, it works very well.
