I was very suprised this stuff actually worked as I developed it when I was painting a huge golden sculpture back in 2014. The art store products I used then yellowed the sky, so I messed around with the mediums and made an oil that was extremely clear for colors like blue and violet. Its sad 'Wisteria' is not able to be seen as it was destroyed 5 years ago, but it helped to develop a technique of using this stuff. I don't mean to hate on Blockx Amber Painting Solution, as its still very good, and Blockx paints along with my own handmade lead paint is what I use as paints. The Blockx Aureolin, Viridian and Cobalt Blues and Violets are better paints than anyone makes for way over a hundred years. To answer your question, the hardest part of Wisteria was when I set it outside one day in 2018 and the epoxide-oil ground started to bubble away from the ground in the heat of the sun. I had to spend about 6 months having to figure out how to reattach this flexible ground that I peeled away from the original ground back onto a piece of wood. I ended up using this slow drying epoxide and oil mixture and using a series of vaccum bags and weights to make sure that it stuck to the wood. It was successful and I never had another problem with it peeling away and there were also no bubbles. The painting was the easy part, that's what I've been doing since the late 1990's, painting and drawing stuff. As well as these videos on here, I want to offer prints and products for some of my other abstract drawings and gouache paintings that still survived all that time, so check out my site in the next few weeks and hopefully they'll be new stuff. Plus I'm finishing up the newest painting hopefully to be done in the next few months. Its much darker and foreboding than this one and I didn't record it at all as I don't have a set up to simulcast like I used to back when this was made.
