My boo-fay painting project gave me fits this weekend....I feel your pain! Have you tried sanding lightly between coats? Hang in there...remember what Nester says "It doesn't have to be perfect to be beautiful!"
I hate it when seemingly simple plans don't go right. What do you mean by "streaky?" Maybe I can help! I've painted everything that doesn't move in our house ... more than once. Including black. Are you applying with a brush or spray?
Oh boy I know how you feel! lol. It can get pretty frustrating. Have you tried spray-paint? I have noticed that with peices that I used to try and paint [large peices anyways] I would get the same streaky look and time and time again I felt like all I was doing was re-peating what I had JUST did. I finally got fed up and went and bought some spray-paint [for woods] and man, it was so easy and I wasn't getting that streaky look I was getting with the paint I was using. :)
Thanks for the words of wisdom! I used leftover flat black paint with a sponge roller (after I primed). It looked rather dull so I tried some wipe on poly over it- that made it look streaky. So I sanded the poly off and now I am thinking of getting some satin paint (I don't like gloss on anything) and starting over. I haven't used spray paint on large items before, but that is certainly a very interesting thought.
I think you'll have better results with the satin finish.I've used black satin spray paint on large items and had the spotty issue - some areas looked flat. It was weird.Good luck!
Can't wait to see the final product! :)
