I am not a big user of fillers but do use Squadron green from time to time to fill corners in wagon kits and similar. I tend to apply mek over it after it has dried to bond it better to injection moulded styrene and also after filing or sanding to improve the surface, it tends to be a bit porous otherwise. I am not too keen on the xylene solvent in the Squadron green so make sure there is enough ventilation. I also have some Humbrol filler which I have been using for similar purposes and have been surprised at how well it works, older Humbrol fillers were awful. I have never found the dissolved scrap styrene to work we as a filler as it is too gooey and sticky then shrinks more than is helpful. To fill larger surfaces I stick on a strip of 10 or 5 thou styrene sheet with solvent, wait for it to dry then scrape down with a scalpel blade before finishing with fine emery paper. A final brush over with mek brings the surface back to a similar sheen as the kit. For patterns for polyurethane I recommend a light spray with Tamiya model spray can - strange military colours bought when on sale work well - on completion to hide the solvent marks which are otherwise visible on the surface of the castings when they come out of the moulds.
