I'm finally ready to actually get to work on my project 86. The interior of the thing is covered in dried oils, and just lots of other 'gunk'. Whats a good substance to use to get rid of it? I'm planning on just removing the seats and scrubbing away. Maybe something like paint thinner or acetone? Any other suggestions. I think after its cleaned up, I'm going to get some of that Herculiner stuff and cover the floor.
