Originally i used it because of the cold weather,after using it for a couple of weeks i noticed that the window`s where coming up better,the problem window`s i mean.I did a job a couple of weeks ago that when i did last time it was cold but not as cold as this time,the last time even though not as cold my Y pieces froze solid and i had to keep blowing the ice out of them,this time it was colder and i had no problems of freezing at all.The reason why i now use it all the time is simply cos of the results,try it and tell me i was right lol.
