Painting mouldings is one of the biggest pains in the ass.
Its all in the prep work no matter how you look at it and if you don't do good prep work it shows up.
Try it again and take your time doing it. We did a friend of mines mouldings and it took us several times to get it right..ended up pulling them off and doing it over the course of a day and a half to make sure everything set up exactly right.....looks perfect a year and a half later.
Oh and the mouldings were black on a white car and thats the hardest color to get to work right because the black bleeds through all the time.
