Who knew that replacing the window seals could make such a difference? Wow! It was so easy to I have replaced the front and rear window seals as they were pretty nasty, now Minty is blinging!! Also, replaced the rear driver side light as they didn't match. Pleased to report that Minty passed her MOT. Happy days! On the other hand, I do not know how you would replace the window seals without one of these remarkably simple little tools that my lovely husband just happened to have in the garage (like you do)!
