Yesterday and today I cut and fitted the aluminium cladding to the right hand side of the front bulkhead. This included the vertical beading. I painted the reverse of the aluminium cladding and beading with the same grey paint as the wood and used seam sealer as well in an attempt to keep electrolytic corrosion at bay.
The vertical beading is incorrect, it should be bisected by the horizontal beading. I will correct this before final paint, but I didn’t realise until sometime later.
