Guys this question probably has been asked dozens of times (and maybe even by me, constantly forgetting things.)   Who uses CH exclusively and if so what are the pros of CH. Same question for those that use CH and SH- pros and cons. I have been very slow to use CH on roofs up to now, but I think the SH I am buying isn't very fresh to begin with and it is also very expensive in comparison to what most guys are paying in the States. Is it possible to almost totally reduce the residue by premixing and then transferring to the truck tank. Also what is the viable life of the CH (mix) v the SH (mix)
