Hopper DDG problem

tried that and it just made things stick worse . Oil is actually kind of sticky . Here is a good test . pour some oil on a metal pan and then pour on some flour or even corn meal . See how much sticks to it . then try spraying with spray wax and you will see a big difference .
Best thing to do is not haul ddg ! I know haul mostly hulls and midds . Sooo much better . Except when it rains since trailer leaks all over .

 

one more thing I learned . A long steel rod to poke down to door or a rope with something small and heavy on the bottom to pull up . makes a hole and then you use a scraper or pole to break off a area as wide as door and across from side to side , Then bump it and it comes out nicely
