Sure. Any mix left? The key thing that you have to do is when you're done applying the paint, go back over it with the roller top to bottom applying no pressure. That aligns the aluminum flakes properly. I think I'd better check and make sure that's in the main thread cause I'm sure not everyone is going to read the HE558 can.
So just go over it one row at a time. And you can overlap these a couple inches each time. It's also handy to have a halogen worklight or some other type of light off to the side shining around 30 degrees or so.
Welcome to the Shack by the way!

How'd you find us?
