Just get some new seals. FYI, instead of scraping the old seals out, in most Minoltas you can dig under the end of the seal and find the adhesive strip. If you can find the end of it you can usually just peel the whole seal right out in a very clean fashion. This goes for the rear channel seals as well as the door seals and the mirror bumper as well! It takes only minutes to replace seals on a Minolta if this applies to your camera. Good luck!
