I personally use any of the structural gels intended for making oil
like marks on canvas or as its more known, Impasto.

My favorites have to be Golden's High Solid Gel, Extra Heavy Gel,
Liquitex Light Modelling Paste and Lascaux Structura. I use these as
fillers for large pieces (such as resin or vinyl models) where an
epoxy putty would either be a waste of time and effort (and more
importantly, money), or where it may be unlikely to stick (i.e.
vinyl).

It helps to roughen the surface a little for these types of things
because they are much wetter than epoxy. I have also had great fun
mixing my own putties when necessary out of things like Marble
Powder, Whiting, Wall Fillers (Spackle to those in the US) and have
even made out out of hair gel! Artist's Gesso is very similar but
finer and not as thick. All can be suitably sanded to smooth with
various W/D paper or a Dremel.

Kindest regards

Elliott
