Though not yet ready for commercial production, the Indiana - based company says that it has developed a bio-aviation fuel made from landfill waste, sorghum, algae and
wood chips which it says will be
cheaper to produce and perform better than current aviation fuels.
Was wondering what you thought of using caulk to fill nail holes and to create a seal between each plank — recessed enough that the plank motif is still evidence but it will give a uniform depth (and fill in those few places where the
wood was
chipped — these
cheap planks do have some duds)?
