After this monsoon type rain my 86 defender 90 has decided it now want to be a sieve. Passesnger seat is fine as previous owner filled the front part of gutter with sealant. I went out this afternoon to find a small pond in the drivers foot well. The drip from usual place windscreen puller about an inch back on the roof gutter join. I've scrapped out old sealant and redone it with more sealant! Hoping this does the job otherwise will have to seal the inside aswell as re doing the seal.
