Aussie members - what's a good exterior grade wood filler?
The skin will be structural ply glued and stapled.
Will be sealing with polyurethane (the mix), gluing and stapling the skin to the frame, then filling nail/staple holes, knots and splits, then painting.
Want to be able to get it from the hardware store.
I'm sorta conflicted - good 'ol no more gaps is flexible, sticks like sh!t to a blanket, is cheap and paints well.
Or there is builder's bog - polyester resin with various fillers.
Or is there something better?
