I have used a "dremel" type tool with a range of bits - this requires patience and a steady hand. The alternative is to blast the seam with sand but this is messy and will also remove good paint adjacent to the seam.

Thanks all. Ive been using the Dremmel technique, and today also found (in Wilcos) a 'grout remover' tool, which looks like a section of saw blade in a handle, good for scraping out most of the sealant.

it pointless doing the outside of the seam unless you remove interior panels & do the back as well--yool never get all the rust out-it will be between the spot welds--
So many with seam issues , my experience has been a baptism of fire , Boris my 24 year old westy came into the warehouse for some light titalation , 2 years ago ! After removing one bit then another to expose the true extent of rot i should have just cut him up & sold what i could & made a we fortune . A lot of the seams appeare to be only lightly corroded on the outside but after removing the inner paneling ( complete interior ) i have found horible tin worm , i have so far replaced front scuttle OSR inner & outer 1/4 panel , wheel arch , rear lower 1/4 panel NRS outer 1/4 pannel wheel arch & lower 1/4 panel . I decided to gouge out any remaining seam sealer around the factory panel joints wire bush & weld up all the external seams & deseam , i will then lather the inner pannels with waxoil . Good luck to you
