Works if mixed stronger than recommended
Just does not work if diluted as suggested. the film left after drying is not adequate for surfaces that are not "shiny/slick" already. I found if I diluted it at closer to 5 to 1, spray on, and then wipe over with a terry cloth while wet, I was getting better results.
I consider good results to be the following. After coming off the track, if I wait approximately 30 minutes and let mud dry some, I can rattle or slap a body part and the mud will dislodge and fall loose. Later when washing the remnant staining washes away easily with a pressure washer and does not require physical abrasion with a cloth or sponge to remove.
