I hope they are not expecting you to wrap the doors as well? In that case, run! You cannot get the handles and bars off, at least not easily when it's a used container. Also, be prepared to maybe use a high tack vinyl, paints on these are tough to get something to stick to sometimes. I agree a wrap is not the easiest on these but on the sides it's doable with some time and patience. But be sure to put some "margin" for a PITA work in your quote! And also the sides require a bit more vinyl than the length of the container due to corrugations. Good luck!
