The booster will fit in the bottom of a 3.5 gal pail with .5 to .75 inches of clearance.
Well, I don't know how big a 3.5 gal pail is, so still can't visualize what you have going. There is no substitute for a good estimate of the booster surface area.

How much distance is there between anodes & booster? You certainly want a lot more than .5-.75" separation between them.

With 36" of anode, I'm getting the feeling though, that your booster is bigger than your anodes, which will give uneven and/or poor plating.

Do I rub off the white rust dry?
Rubbing it off is not a cure, it's just a means of identifying IF it's white rust that you're seeing.

The proper thing to do is PREVENT it from white rusting in the first place, by chromate, WD-40, wax, paint, etc.

Right now I can't go from blasting to plating.Blast at work , plate at home.
In that case, depending on how much time elapses in-between:
  • a few hours - pickle the parts in mild muriatic acid right before plating. This will remove any minute surface rust that has developed.
  • overnight - hit the fresh blasted parts w/WD-40 to prevent rusting. Degrease then acid pickle right before plating.

Will the acid solution you mentioned be correct to strip the zinc and chromate finish?
Yes. The stronger the solution, the faster it will strip. 15-20% is more than enough to strip parts w/in 5-15 minutes (just depends on how thick the plate is). When the parts stop fizzing, the zinc is gone.

Seems like I always have to run my solution through coffee filters.
Why? The electrolyte will get cloudy w/sediments, but still plates good. Filtering does remove the brightener (if you use it).
