As others have said, it really does depend on the paint types and their reactions with one another. Some acrylic paints really react badly with chemical solvent based ones, and the paint will blister, discolor, etc. So you really just need to do your research, learn from others mistakes, so you don't make them, and then do some test. Get yourself some material similar to what you are priming, like plasticard, paint it with your chosen acrylic and then spray your chosen solvent based varnish.

If you go on YouTube you will find loads of such vids. So just do your homework.   

At 65% there's still quite a way to go

Thank you to everyone for your help, it has greatly helped.

I was in the middle of designing some and had that horrible thought I had missed something as it didn't look right, that something turned out to be the font I was using. I had the right height for the numbers however it was too wide. Have found a narrow font while retaining the simple shape of the number 1. There is a lot of narrow fonts however the number 1 is not the same style as used on the cast speed signs.

Re the change from white to yellow letters, like crewearpley40 mention, this is what the railsigns website has quoted "In 1963, following what had been an exceptionally cold winter, BR took the decision to re-paint all cut-out speed restriction signs yellow to improve their visibility in snow"

Blimey, they would look at home in Fireball XL5!
