Wow, great info in here! I've always had my lines blown out by someone else because I never thought my puny 1-gallon compressor was big enough....I assumed you needed one of those huge ones.
And I'm one of those red antifreeze guys, too....it can get 20-below here at 7,000 in the Rockies so don't ever want frozen lines. It does rinse out real well...just put a little bleach into the water in the Spring when rinsing it all out.
