    Thanks gonzo!! Do you also recommend I precoat the wood with the bondo polyester resin prior to glueing it?

    There is no need. The bondo will be a lighter hold than thickened epoxy. The thickened epoxy woukd require grinding the block off or removing it with a bar will break the concrete.

    Eother way will work. It all depends on what bond strength you want. The epoxy method with precoating the wood versus the polyester is ablut 5 times stronger.

    For a temp jig, polyester bondo will he fine. For a jig mesnt to be in place for a yesr, I go epixy.

    Thanks Fallguy! But sorry I'm a little confused, are you saying there is no need for precoating the wood, or no need for mixing the bondo polyester resin with a filler like chopped/ milled fiber? These blocks will be holding up the bulkheads. I plan to mix the bondo polyester resin with milled fiber but I don't plan to precoat the wood blocks. Do I have that right?

    Thanks again to everyone for all the amazing input I really appreciate it!!!

    If you are using these to support bulkheads; just use epoxy and some silica. A bit wetter mix like cake batter about 1.5 silica to resin by volume. So 6 oz resin and 9 oz silica.
