Painting is a time consuming practice, you need to make sure you goo gone the pieces then soap them, rise and dry, after that, BUY KRYLON PRIMER!!! its white, and makes the color more vibrant and it sticks soooo much better...after that paint in very light coats, the first should look like it is just a speckled tint to the white, and continue light coats every few minutes...if it looks bad, wait till it dries, sand it down with a fine sandpaper and prep and try again....number 1 rule....TAKE YOUR TIME....i had the same problem as you too...i dint know how to do it...i learned though...good luck...
