If you are really good with an airbrush, and weathering techniques, you can make the logs look like wooden dowels from the hardware store.....
I have seen the steel coils done up very nicely.. Again.. proper paint, some rust, weathering,awooden pallet and cribbing, meatal banding to holdit in place....
If your painting skills are less than you would like.. you could paint the coil grey, make up the pallet and stuff, and cover it with a Kleenex tarp...alot of steel haulers do this..
