Similar to previous deal regarding ultimate car wash, but this has more quantity for slightly more.
Meguiar's Ultimate 1.42L @ $17.99 = $12.70~/L
Meguiar's Gold 1.89L @ $21.89 = $11.58~/L
Also the Gold seems to be higher concentrated and better for snow cannon.
In terms of whether Ultimate Wash & Wax or Gold Class is better; it has been said that Gold Class provides better cleaning ability and much more suitable for Snow Cannon, however the Ultimate Wash & Wax provides better protection. UWW however doesnt work well with the snow cannon/foam lance.
