I have a water problem and I don't mean me! I recntly patched a hole in the drivers footwell of my classic, I welded a plate in smothered the underside in silicone sealant followed by several helpings of under body sealant, however I noticed a wet patch on the carpet the other day and it has me stumped! Is there any area on the classic which is known for ingress in this area, I have a new windscreen seal fitted so I'm ruling out that area. Is it possible my heater matrix has a leak? looking for some inspiration guys!!
