I found window cling sheets (WalMart) that you could put on the whole back window. It was in the car care section. It does not have adhesive so it is removable without any damage. You simply cut the sheet to size, clean and dry the window, spray with plain water and apply the cling sheet. The hardest part is working the bubbles out so it doesn't look funny from the outside. You sinply need a small squeegy and patients for that. I have even put it on the inside of out bedroom windows to help with the light. (husband works nights!). It is under $20 for a role and you could do the whole back window and probabley a side or two. A.
