Spinal Tap,
When I lite mine up unprimed they catch on corners and spread.
Fair pop.
I coated with ****mizu's Egg prime and they went turbo.
Very loud, and fast.
I put a coat of green mix BP with Silicon on last night and should be
dry in a few.
When I found that 81.8 Trioxide works, I've made 3 batches and all
work great.
With all the shooting last night, it ought to be crazy tonight.
Be careful,
Dan
