I got to see Roger's presentation a couple times and they were great!
If you are doing graffiti removal or want to get into it, there are a lot of things that you should know but most out there will not tell you or don't know themselves and that is the info that can potentially save your life when dealing with graffiti.
There are many situations that could bring you into danger when dealing with graffiti and Roger shows and explains how to deal with this to keep you safe and making money.
There are some things you can do that will not cost you any money but will literally have the law watching your back as you work to keep you safe when dealing with dangerous situations, again, learn this from Roger instead of learning the hard way!
There are a lot of products out there and I have tried a lot of them. Save a lot of time and money by listening to what Roger tells you and shows you what works, we all hate to waste time and money!
If I was going to this event I would be watching this presentation again, it gets better and better each time!
