We used to put a food dye into our Copydex when laminating wings so that we could see where we had missed with the adhesive.
Just a thought but is it surface tension that is causing your problem? A very small drop of washing up liquid? I have never tried this so test the idea before using it!

I too used to dye the glue for the same reason using the blue stuff used for fish tanks, I think it was intended to kill the little parasites in the water.
My problem with the Copydex is that it paints down onto the substrate O.K. but peels off so easily. I use it for glueing the vinyl,(faux leather),onto usually balsa or very
thin plywood. The last time that I used it successfully was 2011, making the upholstery for my Riva build which gave no problems.
This time, whilst building a larger version, the adhesive is very different, although it seems to adhere reasonably well to flat surfaces it doesn't have the strength to hold the folded over parts This wasn't a problem on the older version.
I think that the recipe has been changed to suit the Health and Safety regulations and like many other products just isn't the same, Nitromors is a prime example.
