So I have searched this site and all the old threads, I have googled and searched other sites. There seems to be 2 diff opinions out there about mixing oil based and water based compounds. A lot of the threads are just one person after another repeating what someone else said or something they've read. I have been trying to find some type of study or scientific evidence that puts this question to rest. Does anyone know of any such material? Some have mixed with good results and some with bad. There are a lot of variables to consider in determining why there is a discrepancy. Thats why I'm looking for a scientific explanation. Maybe someone has done a search and found what I haven't been able to.

Thanks in advance.
