...and spoke with a guy who I assume had been mixing paint since the 1970s (when it was a skill rather than just pushing buttons on a computer keyboard). He was very enthusiastic about my little science project and pulled out loads of colour charts. He kind of repeated the information that his colleagues had made earlier on in the week by saying that a thick coat of the top colour coat is eventually going to have an effect. He said I should apply some really thick paint to see where the limits are for the colour coat I want to use.
So I did this =>
This time a bright orange top coat colour was used on top of the light beige filling primer used in the previous investigations.
I applied a really thick streak across the three sections here =>
You can see that the colour is patchy - heavily applied - three thick almost dripping layers - and now there is no under colour effect.

This got me thinking. I'm definitely a DIY paint spraying type of a chap. I have both feet firmly in the "
spray it as evenly as you can - wait for it to dry - wet sand it - wait for it to dry - spray over the holes in the colour you've just made - wait for it to dry - wet sand it again - etc - etc" camp so the chances of me being able to apply an even thin layer on top of an other colour is pretty slim at the moment.
For this reason I'm passing the baton on to someone else! I'm not going to go any further with this investigation just at the moment. I will, however, post my plan of attack to try and get some understanding in this "art".
