LED in a ds...?....i never thought of that...maybe ill try it when i get a new soldering iron
Anyways about your paint issue.
Go to lowes(i recommend because its just better i think) and pick your paint.
Then pick a polyurethane finish. (you can also find this at craft stores)
*warning* I dont recommend spray laquer unless you want to blue tape all parts your dont want to hit. *warning*
Other than that.
After you buy your polyurethane.
Pick up some disposibal sponge brushes which should be in a pack of 30 ect ect
Then add about 4 coats on to really get a nice glossy look and feel.
Let dry over night inside unless its cold.
Humidity will make the drying process take longer.
Hope i somewhat helped.
