I started using powder about 18 months ago over vinyl myself. The first problem i had was get the powder to cure right. I started to cure mine at 400 degrees and that "cured" my problem. I dont use white as a undercoat, but do use it on swim jigs and spinnerbaits. It looks as good as the vinyl, but the powder paint is ten times stronger, tougher than the vinyl. The nice thing about the powder is you can mix colors of powder together to get a custom fish catching colors. I like to mix black and blue to get a nice mixed head color. You can also use one color than dip the top of a jig in to give it a highlight color on the top of a jig. After using powder i would not go back to using vinyl again. I also dont currently have a fluid bed and dip right in to the powder jar. You will want to shake you powder about every 6 heads to prevent the powder packing.
Hope that helps.
