The tricky part with under coating is the mess you have to clean up afterward. When it cold you can chip it off better. We usually mount the body on the rotisserie and turn it up side down and coat the hard to get under coating with diesel fuel and let it sit and scrap it off a little while later. We do it over a cheap tarp we can later throw away. Then send it out to get blasted in the hard to get areas. Seems to be about the most time sensitive manner we have found. Pressure washer seemed to make a whole other mess that now has to be cleaned up.
