I carry the box of DEF. auto-zone has best price where I live. I only use Wofgang products on my Show Cars and the F450. Great products work perfectly with new vehicles and clear coats. My truck get 115 for days on end! Looks new for ever! I also "never use or allow buffers"! It's done by hand.
Your love the truck!
