Polyfilla will probably dry too quite quickly for your experiment. You
might consider using 'One-coat' plaster which is workable for at least 30
minutes and it will be cheaper than Polyfilla if you have to abandon the
idea.

Thanks for the tip. I just happen to have some of the Wickes' variety!
Usefull stuff. It doesn't seem quite as smooth as polyfilla when wet.

Mixing a plaster filler and paint (usually gloss / undercoat) used to be
called 'Swedish putty' and was used before modern fillers became available.

I vaguely remember hearing about that. I wonder if oil-based paint is
better than water-based for this purpose. Whichever one ends up with
the most flexibility and adhesion, long-term, would probably be best
for this job.
