Mark ,
that same award winning cleaner . also did a test with encap and bonnet side by side,
cleaned with bonnet, then an area with encap.
went over both areas with bonnet ,
result dirt on bonnet and no dirt from the encap area,
I was with him at the time, and the same award winning c/c was also the man who introduced me to encap.
as for the stains returning, have had no complaints so far.
and even got the job of cleaning and maintaing a number of health clubs using encap.
why because the manager, was so impressed with the results in comparison to other previous cleans he mailed all of his work collegues with my details.
geoff.
ps.Micheal, hardly extra cost a simple edging brush, but just incase you were refering to the extra cost
involved ie time factor, the speed of encapping more than makes up for it.
