As usual 0.06 layer height prints first airbrushed with the mentioned chemicals, but due to little to no effect using that method I decided to brush on the chemicals instead quickly and then airbrushed them lightly with a primer to see the effect of each one afterwards. Methylene Chloride turned out to be more effective when applied in smaller amounts compared to the other two!

I may try and see how 0.1 prints take to methylene chloride, but there will never be as much detail as in 0.06 prints so it defeats the point in doing it in my opinion. This is because I am trying to get high levels of detail and surface smoothness at the same time whilst saving material costs using PLA for my prints which is a very cost effective material.
