how do you paint gold and or silver on fondant with out it looking streaky? i have used glaze and powder with alcohol but the glaze pulls off when i try to do a second coat (even after letting it dry for more than 30 min) and the powder is streaky and has darker/lighter spots.

any tricks or products that work well?

I've had really good results using veg oil instead of extract or vodka/alcohol, it leaves less streaks and covers better, the down side is it never really dries, so don't touch it after you paint it.

Lemon extract is great for painting luster dust and getting fewer streaks.

The minimal amount of oil makes it go on smoothly, but it still dries well.

I tried using it with vodka and after a few applications I let it dry a bit and then I dust the dry luster dust on it to finish it and it seems to cover the streak a bit.

Try coloring your fondant a shade lighter than your glaze. I just used silver today for a baptism cake so I colored the fondant a light gray and put two coats of silver glaze. Looked perfect. For gold I use golden yellow fondant.
