As Mike as pointed out I do tend to do alot more encap and do make good money from this method,
when ever I survey commercial I push the encap, I give a quick demo , as it takes literaly a couple of minutes to set up and to reitiriate Mikes point , the results are visibly stunning , this can make all the difference in getting the job.
The only drawback I will point out, as some may jump in and start knocking

the system , is the critical pre-vac, requiring a visit the next day . This not alway been Ideal because of the logistics, however I have never ever had to visit the next day because explaining the method to custy,s and the importance of post vaccing they are more than happy to arrange with in house cleaners .

ps.
and thanks to Mike for introducing me to encap.
