Ok, so get a straw or a piece of shrink tubing, and fit it over the nozzle. Put the other end in a suitable container (I use old tamiya paint jars, cleaned obviously, then spray out as much as you want. Leave the lid off for a few hours so that the propellant can off gas, then you are good to go.

Jakko, it involves using a tube from a disposable drink sachet which is about the same size as the rim around the nozzle. The top of the jar is sealed off with tape and you then push the tube through a small hole in the tape and gently spray into the jar from the can. Then you let it bleed off the gas.
Only tried it once, spent the rest of the day wiping myself down as I forgot to hold the tube in place..... But there are plenty of tutorials on YT explaining the process.Comment

There's probably a simple answer but why use Halfords primer rather than a dedicated modelling primer. Is it better or cheaper?
MRP (lacquer) or Stynylrez (acrylic) are airbrush ready and work very well. Even if an airbrush isn't available there is Tamiya fine surface primer in aerosol which is very good.
I know many swear by Halfords but I just wondered.Comment

Generally non- model branded plastic primers are cheaper, sometimes a LOT cheaper.
From your examples, you can get 473 ml of Stynylrez primer for about £28, compared with 400 ml of Hycote plastic primer for about £16. The Hycote is a fair bit cheaper (4p/ml compared to 6p/ml) and becomes a lot cheaper if you buy smaller amounts of the Stynylrez.
It's a point illustrated by comparison with MRP's primer. I can only find 50 ml bottles at £6.50 which would make it £52 for 400 ml. The MRP would have to do something pretty spectacular to justify that, and in my experience it doesn't.
I've never had any issue with either of the plastic primers I referenced (Halfords and Hycote). Whether they are better or worse than the branded items is going to be a matter of opinion, but they are at least as good as any I've used.Comment

Well the weather has permitted me to get in the garage today to try the Halfords. Also decanted some (that was messy) as will brush paint smaller parts.
Don't think it's done too bad a job for first time. Will need to get some thinners before using in the AB as white spirit was struggling to get it off my hands.

I just use a drinking straw sealed to the nozzle with blu tack. Works well! Amazing how much propellant gasses off though. I tend to decant it to a jar then leave the top loose for an hour or so until it stops bubbling. The paint solvent doesn’t gas off much because it isn’t as volatile.Comment

Yep, used a drinking straw but sealed with tape, well not sealed really the amount got on my hands. lol. I'm guessing it's still cellulose based as a right job using white spirit to clean up.
After reading a couple of other threads concerning paint booths and smells (I share the room with SWMBO) I'm thinking of trying one of the recommended acrylic primers.Comment

White spirit would only really clean up an enamel or oil based primer. Cellulose or acrylic wouldn’t be dissolved by it. I would expect the Halfords stuff to be acrylic these days, but could be wrong LOL. Most people seem to get on well with stynylres so I’d go with that if I were you.Comment

Just done the obvious, look on Halfords site, duh. It's acrylic base. So just need to perfect the decanting and jobs a good en. It does seem everyone has their go to primer. Had a look in the shop, and John say that the Stynylrez is discontinued.
Read a review on the Styn and they reckoned that the Mig One Shot was the same stuff...Comment
