You may want to make sure you wear old clothing and some sort of gloves, this stuff is real hard to get off when it gets on your skin, if you spray wear a good respirator it is real bad for your lungs.
If you have not ordered yet I would recommend ordering the smaller cans, after it is opened it is hard to preserve the left over. Some have good ideas as to how to preserve but it doesn't always work and you could waist a lot.
Anyway, that’s my 2 cents worth.
