Best- another vote for Future and Tamiya paint. And I like the way some Vallejos smell.
Worst- "odorless" turpenoid. Yeah, it doesn't have much smell, but that didn't stop me from having an allergic sinus reaction from the ninth circle of hell the first and only time I've used it to try some oil washes.
My favorite non-modeling smells-
Old books, especially very old comic books. And of course the smell of a Half Price Books store.
The smell of any piece of meat covered with a Cajun spice mix that I use and then thrown in a hot skillet.
Hickory smoke in my back yard. Mmmmmmmmmmmmmmmmm, barbecue. I'll be smelling that in probably 8 or 9 hours.
Oregano.
No, I don't like to cook.
