“Do you ever give anyone an answer in layman's terms?”
Yes, when I talk with people who aren’t industry participants.
“Seems like DuraShield is better (than dri-brite)….”
Operator charges $5.00 for wash and it contains dri-brite as drying agent.
Operator charges $8.00 for wash and it contains dura shield as total body protectant (no drying agent is used or needed in package).
($8 - $5) - $.75 cost = $2.25
“but is it worth 4x as much better?”
It would be worth a lot to me.
The reason is you can’t sell drying agent as total body. The difference in the effects produced by the two products is too evident to consumers.
Super shield contains aliphatic hydrocarbon, ether and quatemary compound.
Is super better than dura? What makes it “super”?
Reportedly its exclusive additive, Body Armor - allows the protectant to adhere to the surface of the car more completely and build a thicker level of protection.
These characteristics are identical to other products like double bond which is a fluorocarbon coating that imparts surface tension reduction properties.
So, asking if super is better than dura is like asking if double bond is better than rain-x online.
Throw in price less cost and it’s difficult to answer in layman’s terms.
