Philip-
Appreciate the kind words . The lack of a moderator has caused problems for this forum several times . You are free to take over and revitalize it . I don't have much new to add, unfortunately .
FWIW......My latest experiment was wiping on a quick coat of Zaino Z-CS Clear Seal . It is the easiest and fastest stuff I've found to apply and it shines brilliantly . Keep in mind that it contains no cleaners so you have to spend time polishing or otherwise preparing the surface before applying it .
Zaino Z-AIO ( All In One ) can be used as a one-step sealant and can be applied by machine . It should be faster than a two-step process ending in Clear Seal .
I used Zaino Leather Soft cleaner on the seats . It gently cleans and adds some oils to the leather . It won't take the place of Zaino " Leather In A Bottle " but it will allow a pro to quickly detail leather .
I tried using gas station blue paper towels on the interior windshield with lousy results .
I brushed the carpeted mats with Simple Green and pressure washed them . Some road tar remained on one mat, so I used Stoner's Tarminator to remove it ( some brown staining remains ) and washed it again to remove the odor of the Tarminator .
