The curly hose is nice for show but I had trouble with it freezing in the winter. The hose length (35ft) was so long, the chemical/foam would flash freeze in the hose before it could get to the gun. If it made it to the gun, the tip would freeze it. This didn't happen until about 15° or lower. Living in Southern Ohio, it can get a lot colder than that and for an extended period of time. So I switched out all the hoses with straight 3/8 Good Year air hose. Lasts for years and is plenty pliable in colder weather. Its even debatable if there is any difference in performance between straight hose and curly....
FYI, I don't weep or use methanol mixtures...I use a blowdown system using air and washer fluid...The tradeoff is well worth it. I used $75 worth of washer fluid last winter for 8 hoses....(4) guns and (4) foam brush hoses...Not a single freezeup....
