Looking good Iain. Now the hard yards start with all the painting and polishing you want to do. Your effort will be all the worthwhile once she's all done and looking schmick. The Yammie is a good looking jigger. One of the best from the era I reckon.
Dave, why totally strip the paint off the tank? If it's still in good nick, just sand it back with 320, apply 1k primer and then colour within 20 minutes of each other. Or, wait for the primer to dry, sand with 400 then add your colour. If you really need to strip the tank, paint stripper and a wire brush do wonders. Be sure to thoroughly wash the tank in soapy water before you start prepping for paint.
