My self- I wouldn't consider doing it even for a friend. The wrong person sees it, trouble can arise. As an ex Mobil station owner/operator for 39 yrs, I had to get mobil's permission to use ANYTHING with "Mobil" or the emblems they use. Years ago they came out with the Mobil Round dispenser [pump]. I wanted to get rid of my old ones & get some used ones from a company that did station remodeling. Had to get Mobils' permission to buy them. Because of what I've writted & I wasn't a company owned outlet. Any signage, same thing. Bought a co-cart for the kids that was like an Indy Car. Had to get special permission to decal it with anything of Mobil, or any decal that matched Rick Mears's decaling. "On a GO CART?" What was explained was 'anything that is publicly displayed, used or can be seen by others without permission is illegal.' Collectoe's items, banners, etc. are ok because permission has already been granted. Bunch of BULL as far as I'm concerned, but.....
