Generally you'd push with mig, pull with a stick although there are times when the mig pull technique is required.
For thin stuff like bodywork, push to reduce the penetration and the risk of blowing through.

I think they say to run flux core as a drag or pull.
Though I hope flux core is not in the plans.

Never having done any welding on cars, would it be more sensible to weld downwards when in the vertical position? As welding upwards, with the heat rising, you would be welding into progressively hotter steel and therefore increasing your chances of blowing through?

I find it easier Marty, but at times up is preferable (slows you down so you pay more attention)

I mig weld anything less than 5mm downhill and push gives better gas cover.

No ramp in the garage, so laid down next to the sill I sometimes find up easier, but not often.

I concur with your findings

Yeaaaa down the way, less penetration but not needed on car.
