For use above the waterline so that it does not contaminate paint colour, i.e. showing tramlines through the paint. However with modern paints such as METACLOR C.R. Primers two coats of this and it hides just about anything from my own experience. The mix is usually 60% White lead with 40% putty added to make it go further. When you have a good ball mixed add a thumb nail of motor grease and mix in well. This will slow down the drying of the putty that gives the cracks one sees in old seams.

Can be used straight from the tin/keg with a pallet knife into the seam. If when finished "fairing in" dip a clean pallet knife in Linseed oil and work back the other way. It will iron out any little holes and leave it like a babys bum ready for the primer paint

To those of you using this for the first time fair/sand your hull FIRST and then when "fair" apply Red Lead Putty Do NOT sand over. When the seams are done apply lightly a coat of primer paint to seal and then you may undercoat and Gloss paint.

For mixing in with linseed oil putty and stopping seams below the water line. Again a small amount of motor grease added will help.
