I used to do the same, using Humbrol model paint on carbon paper trace. For simple things I would paint direct on SRBP. No glass fibre.

Back in those days I used two methods:
Copper clad FR4 was available, but a lot of SRBP was used as it was much cheaper.
The first method was to paint, by hand, using mothers thinned nail varnish onto a carbon paper print traced from the layout printout.
