Some food for thought on spray bars and pattern's. A cheap pump could be had
from a washer fluid pump [ think this is what Tracy used??] A easily had
spray nozzle could be had from various cars. I've found that some of the
nicer European cars [BMw or VW] w/ the nozzles mounted on the hood get a
pretty nice pattern. Another place where a guy could get a nice nozzle by
using nozzles from Agricultural sprayers. Different patterns and GPH can be
had quite easily.

my 2 cents
