Radiator Flush 2C

Anyone have experience with getting preventative maintenance on the radiator system? I was going to use a local radiator specialist and before I swing by, I was wondering there were major do's and dont's. Everything is in working order, just trying to stay ahead of the potential nightmares.

Just bumping this question. Also wondering what coolant folks are using for best cooling results. And while I'm asking, what is a safe maximum coolant temp to run for extended time periods without risking head gasket failure?
