    Hi,
    I am restoring a 1954 30 foot sailing yacht. It was caulked using cotton, and then red lead/Linseed oil putty. The boat has been out of the water for some time and the red lead/Linseed oil putty has gone hard and cracked in places.
    I would like to redo the hull using a modern seam compound (Interlux). So I need to remove all of the red lead/Linseed oil putty mixture first, or could I simply apply the seam compound over the red lead/Linseed oil putty?
    If the advice is to remove it - anyone got an easy way to do it!

    I was afraid you'd say that!!
    If I remove it all am I better using a product like Interlux seam sealant instead of red lead/putty?

    I don't think you have the option of using red lead.

    Modern seaming compound is far superior any way.

    Modern products are much superior to linseed based putty. However, the surfaces need to be clean and primed.

    Make sure you go with the grain, a screw driver with a right angle near the tip the thickness of the plank, a butter knife, used sometimes vertically to gain leverage for the screwdriver and if your careful a jigsaw with a plank thickness blade that has speed control. It has to remain dry , or the timber will expand making it more difficult, careful of those ribs,..!

    Just out of curiosity, why would sound caulking need to be removed ?

    Certainly don't want to be removing what doesn't need to be removed, a bit like people who strip paint back to bare boards, frequently just making work for themselves.
