I used to joke about creating spray on mud as my million dollar product idea. Macho up your suburban assault vehicle with some many mud splatters without getting your hands dirty.
Yours truly, former owner of a ridiculously lifted jeep that's been all over the western half of the US and regularly went up & down dry creek beds with 1+ foot vertical drops/climbs that needed the clearance. That thing never saw a clean day. Hose it until there's no longer mud on the door handles.
