Sammy, you should know all the details about something before making comments.
IRB can come and go. Fine mesh resin has a higher pressure loss than the same volume of regular mesh resin.
My prospective customer won't buy from a local dealer and 98% do their own installation and, they do not want to call a local dealer to fix their equipment because of the price and the possibility of the dealer or his service guy getting it wrong. They want to fix it themselves.
A person that wants to depend on a local dealer for sales and service won't be contacting me or buying from me. Thereby it doesn't matter where in North America or Mexico I am as long as I have cell phone and internet service and you shouldn't concern yourself about me or any of the things you seem to be going on about.
My qualifications, ummm I hardly have any book learnin' and the last was like 19-22 years ago, no licenses, I don't do no stinkin' installations or what you call service and I got no books of my own. I guess that's why I only do a quarter mil of sales a year sitting in my briefs if I care to, in my motor home (currently in SW AZ at $2.87 per day [yes $2.87]), on my cell phone for an hour to an hour and a half with each prospective customer teaching them all about whatever types of equipment they need and taken' credit card info and shippin' addresses. Maybe that's why only 7 or 8 out of 10 people that call me buy from me. If you think I could improve all that and you want to make suggestions of how, I'm all ears as they say.
