Ok LM, same difference, it,s called a dry system as it utilizes hardly any watre (except in pre-spray) Lm, dry, it´s splitting hairs.
It can usually take about 20 mins to dry but I gave that as a guide, it depends on weather conditions, ventilation etc.
I guess i would charge aroubd the 800 quid mark, depending on the situation, you are on the ground, so you will have the better idea.
What¨s it not good for... Suites!
i have used it on everything from soot, to pubs, resturants, EOT and salvage and I love it.
Dry systems are not for everyone, people don´t seem to think it cleans deep.. I have seen different, but hey each to their own
