Default Re: metal prep NEED HELP PLEASE

When you guys use Ospho, do you spray it on and let it dry? If so, how do you prevent the thick crud that accumulates at the bottom of the part?

Or do you let the Ospho sit for a while, then rinse?

I tried the second method once and seemed to get a thin layer of rust when it dried.
