Re: rotting wood
I have had some success repairing rotten wood that cannot be removed.Assuming the rotten wood is not in a critical structural position.<br />I drill many small holes about 3/8, like swiss cheese.<br />Then mixing West System epoxy (my favourite) with just enough fibre mixing powder, Not micro spheres, but a glue mix powder. The idea is to thicken the epoxy just enough to still be liquid, then filling an epoxy syringe with the glue and injecting it into the many holes drilled in the rotten wood.<br />When this cures the result is incredibly hard, hard enough to hammer!<br />Remember to smooth the surface before the epoxy sets as it is hard to sand. Sand a little then hide the whole mess behind a coat of paint. <br />Same technique can be used for plywood delamination, drill into the cavity,then inject epoxy.
