Hey John,
No worries my friend. I personally cannot understand why someone with a truckmount would want to use a pump-up for pre-spraying. A Hydroforce "type" sprayer puts the pre-spray down at a higher temperature and pressure yet is much faster.
A pump type sprayer is good for protectancts and such becuase you can be much more precise with it with regards to dilutions and coverage.
Just my 2 cents..
