Hi all.  I have inherited a 6ft long wooden model boat built in the late 1940's that I am attempting to bring back to life.  The wooden planked hull is sound but was covered in canvas that is rotten and I believe epoxy resin would provide a modern waterproofing solution.
Questions / recommendations:  would a epoxy coating resin suffice or would it be better to use a glass surface tissue or a filler powder ( microballons ) for durability ?    Is it possible to add a pigment or is it preferable to paint the resin later - to keep the boat original it needs to be sand coloured.
Any advice greatly appreciated as boat too precious to make a mess of it. 
Cheers.
Roger.
