I'll be experimenting with the veline color system this week.I'v been looking at step-priming but,i have all the chems needed for the 'veline style' prime so may go for that.I can source dichromate for the 'super prime' but don't want to go near the stuff,for good reason.

I have a question with regards to wood meal.If it's there to make the stars "fuzzy",could MDF dust(70-80 mesh) be used instead?As it is light and "fluffy".

MDF dust would probably be OK, but don't quote me on it. I've successfully used the veline style prime on this thread with (and without) woodmeal (sawdust) on veline stars. I've also had no ignition problems when (due to lack of time) I didn't add a layer of BP over the perc prime.

I imagine anything puffy could work. Even ground vermiculite could work just fine. A word of caution, I never get my stars to light fully without a later of green meal over the super prime.
