The best way i've found to stop the wife from asking too many questions is to get REAL technicial on the stuff yougot, and the stuff you need....like this......
"Do you really need that? You got 7 bottles of wax already."
"Well, this one is for the micro-fine swirls that are under the sub-sonic layer of the clear that, for what ever reason, the manufactor decited to use an ultra hard polymizer with added hydropolic bonding agents that makes it about as hard as buffing shark skin."
"This one is for polarizing the novatrunion molecules that essientally breaks open the bonding cells for that ultra-super fine finish, and this one utilizes the super-micro-abrasive-technology that was patented by the company for ultiminum bonding of the upper layer of the spurbin. So yeah....i NEED it."
I can guarantee that before you even get half-way thru this, she'll give you an eye-roll and go back inside.
But just in case she decides to hear you out, you beter memorize it.
