I've read a lot of threads about winterization. Some say blow the lines, some say fill the lines with antifreeze. But I still have a few questions. I'm sure I'll get a number of opinions, but I fig...

Thanks for all the great info. Some have suggested dialing down the air pressure before blowing the lines. Unfortunately, I have a Superflow MV-50 air compressor that isn't adjustable. It's rated to 120psi, but the manual doesn't say what the output pressure is.
Also, I have read in other posts that some use de-icer windshield washer fluid in the p-traps and gray/blank tanks. I wouldn't use it in the lines, but the other posters say it's cheaper. ($1.50/gal vs $3.50/gal) Has anyone tried that? (please don't blow me in place. Just asking)
Also, my 5er has the Glacier package, so the entire underside is covered. Probably doesn't make any difference when the furnace isn't running.
Harbor Freight has a very nice, quite capable air pressure regulator that can be installed in the output of any air compressor. they also have a filter/dryer. In fact, they have a kit that combines the two in one box. I had them mounted on the side of my toolbox years ago, when I worked for a company that a water problem in their air tank that they didn't want to fix. Big air dryers are pricey. The little one worked just fine, kept a lot of water out of my tools, and dumped it on the hangar floor.
