Question for body guys here about paint..

I used my cleaning thiner i believe, duablabuild primer, but I must confess I will use a regular primer thiner when doing my body work

Yeah.. i overthink stuff... i still need to get a lot of grime out of my engine bad then sand/prep... that grime doesn't wanna budge. all down by the frame.. tried like grez gone and a few things but it's not budging.. might just use a paint stripper wheel at this point
