I wouldn't, I've never had a problem but you might break a small fragile part if you do, I would get a can of Halfords primer, but have a few practice sweeps on an old toy, or something else to get the distribution right, you don't want runs, destroying your hard work.
another point with regard to primer paint worth mentioning Rob, spray sub assemblies rather than un assembled parts, it's easy to scrap a bare patch on the hull through the primer to fit a sprayed and assembled bogie, the glue doesn't stick well over or through the primer, it does on occasion, but its best to scrape the primer clear and glue plastic to plastic.
Ta for that, I find it strange to prime models nobody did it years ago.
standards have gone up 100%, modern acrylics are terrible if painted onto a bare plastic surface, even enamels go on a prepared surface far better, and if you are doing multi media, the primer allows the paint to take evenly on all the different materials like PE or resin. Your ole Dad would have loved Halfords Grey Primer, all the home made stuff he did.
yes I've tried that, it's good if you have a lot of spraying to do in a few days, if like me, you want a quality can to stand on the shelf in the garage and be as good six weeks later in small spurts here and there, every now and again, the epitomy of model makers, then paying the extra for the Halfords one is good economy, the cheaper one's tend to block up, and you only find this out right when you want to use it.
Find out tomorrow, I’ve got a part used can in the shed. But I do tend to wash out the nozzles on spray cans after using.
It seems a fairly sensible place until trying to run with it I imagine
