it seems like all your views are spot on!
1) testing period was not long enough
2) other then including the tire shine the concept has been out there for better then 10 years. the new wrinkle is introducing it to iba operators.
3 i saw the package at the show, it is to tight. the tire shiner is 100 % under the air dryer. not a good idea. better a 40'-50 equipment/ building passes on that.
also in the cold climates freezing is a area of concern. overhead
doors need to be added with up/down operation. even coupled with a great heating system if it's housed in a 50'-60' building and you do volume it's tough not to freeze.
