Here'e what works for me.............
I've been using the 303 & the 1Z Cockpit Premium ( CP as a QD ) & the 1Z Tiefenpfleger on the interior of my vehicles (dash,console,panels, seals etc. ) for a number of years. I rotate between the 303 & the Tiefenpfleger just......well....because I can! lol One product I really like to use that restores window seals, mud guards & my bedliner in my truck is the Meguiar's #38 Tire & Trim Dressing Gel. From time to time I'll "top" the #38 with 303 or Armor All on my bedliner for some added u.v. protection from the Texas sun! As for the tires...... I've used Armor All for years. I like the natural deep black look of it on the tires. ( the oily look is not my style for tires ) What's funny is I've never used Armor All for the interior of my vehicles.....just tires & trims. I'm now using the Zaino Z16 on the tires. It's a terrific product IMO. Just like the Zaino polishes.....a little goes a long way!
In closing.....try the 1Z,303 products.......and whatever you do.....Give the Meg's #38 & Zaino Z16 a try!!
