I am about to have the interior redone on my P15 and have some leaks when washing the car. Need to get that fixed first.  The rear vent windows and door seals seem to be the problem areas. I replaced window and door seal rubber 20 years ago (Steele Rubber).  Should I remove and replace the seals or try some a different adhesive?  Any hints on finding the exact problem areas and applying new adhesive?
