    I'm using Zinsser Bin 123 for my primer on existing oil based paint. I have a 2.5L can of Dulux Primer/Undercoat that that is 3/4 full that I'm intending to use as the undercoat. Just wondering is straight undercoat better than Primer/Undercoat as an undercoat?

    If you already have it use it, primer is for sealing new timber, primer/undercoat will tackle both well. Primer undercoats are water base products.
