But how to get it to atomize ? Thoughts anyone?
We spray a bunch of that at work. Usually Woolwax, Fluid Film for the "full job", inside the doors, under the tail lights on cars, salting equipment, snow removal equipment, etc. Fluid film "creaps" real well for stuff you can't get to well, Woolwax sticks a little longer on the open bottom side. Splitting hairs probably. We've shot some Surface Shield, it hasn't been out (around here) long enough to tell any difference. They all spray the same. They don't "atomize". In fact, I don't think you'd want that. Even the nozzle doesn't atomize. The "purpose built" guns are just a siphon, air blows through a venturi, draws up the material, and the whole slobbery mess just comes out of the gun's nozzle in very coarse drops. (Relatively speaking of course). The "wands" are just quazi stiff open tubing, and the tips of said wands are just drilled holes. The mix, mostly air, and lanolin slobber just blows out of the holes as is. Like one giant hour long continuous uninterrupted sneeze. (About the same as the modified nozzles do). I know DIY has been done, and it's not rocket surgery, so by all means add up what you have and what you don't have, what mechanism and knowledge you have to modify any equipment you have or would get, and tally the dollars. It can be done, and (after you get the snot through the siphon), there is nothing complicated whatsoever. But a couple of our better guys went at it, couldn't build sometning for what it costs to buy a dedicated sprayer. Yeah, those ninety dollar sprayers feel like all of about two dollars in your hand, but if you throttle the air back to where it acts right, they get the job done pretty efficiently, and with minimal mess. FWIW, we have far better luck with those cheezy brass knurled handle ball valve type air line throttles than we do with regulating the air down to any recommended number. You'll know the spot, where it sprays real good and there's no overspray. It's not like dialing in paint, it's not that particular, you've got a good window, and there's not too much art to it.
