If the rear window needs replacing, you need a new top. At best, any "solution" will be temporary and never look like new, as it is just not possible to match the original stitches. Furthermore, most of the labor is removing the old top and installing a new one, so there is no labor savings for re-using the old top.I need to replace my rear window on a 74 Spider. How can I do this? Must the top be removed or can the window be replaced in situ?
There are polishers that are made specifically for the plastic window, and they will make a world of difference... Not sure which are the best today, as my windows are in pretty good shape, but I have always used Meguiars. (See their web site for the heavy duty products.) There certainly are other manufacturers with products which BB posters have praised, so I would also encourage you to do a search.Just a thought, because mine needs this big time. Has anyone tried to use one of these headlight polishing kits for their Spider rear window? You can buy them from Mother's or 3M at all sorts of auto parts stores. I've used them on headlights with good results, but not sure about plastic windows.
