    Why do people condem acrylic primer

    Just because some are incapable of setting the air pressure and thinning the paint correctly it seems we should be forced to use the new range of lacquer shake and go paints these are apparently complete no brainers , though in my opinion bloody expensive ,not all of us work from magnificent man caves with spray booths to cope with lacquer fumes and stink ,rattle cans are OK I used them to prime when I started but tremendous amount of overspray half the can misses the target after all its meant for car door /wings touch up then all that decanting gassing off then put it through your airbrush why not buy a tin of primer and use it from the tin must be cheaper.
    Whats wrong with acrylic primer there's a good choice out there or is it just people cant use it because well because I still can't fathom that bit just because some dont get on with it they shouldn't keep condemning it almost to the point of my way or no way.
    To thoes starting out it must make them want to jack before they've even started there's nothing wrong with acrylic primer you use it the same as all your other bottles/jars of acrylic paint the airbrush procedure is the same correct thinning and pressure

    I dont think I'm doing anything wrong im quite happy with the results ,if people aren't able to use it fine but don't condem it as inferior to the product you've found that suits your capabilities better its a primer and it primes plastic as good as the next one.
    This will no doubt bring down the wrath from the few but as I said why do people condem acrylic primer if YOU can't use it fine move on im glad that there's a alternative product to suit your capabilities but thousands out there are more than happy with acrylic primer and paints.

    David,
    I agree with you - I use acrylic primers exclusively, and I often wonder why other modellers have problems with them! I don't like the smell of thinners, living in a flat. it lingers too long, and it wasn't until water based paints became widely available that I bought an airbrush.
    As an aside - Royal Mail won't accept cellulose/lacquer paints/sprays for normal delivery, so you have to pay a premium for courier/special delivery - which doesn't apply to the water based variety!
    Dave

      Are there people who condemn acrylic primers in general then David? I've seen a lot of criticism of Vallejo primers, which I happen to agree with as it doesn't adhere well and won't sand to a feather edge, but Stynylrez seems to be popular. I haven't tried that Ammo One Shot primer, and I won't, because I've had problems with Ammo paints in the past.

        I do not condemn acrylics. And I find they have their uses, but not for me the primer. I have either had a bad batch or there was a fault with the primer itself. I have sprayed two models with acrylic primer and in both cases the finish was not what I expected. I had to sand down the primer to get a smooth finish and even then I was not happy with the end result.
        And so I have reverted back to lacquer/enamel paints and primers, but I do use acrylic for detail painting. But this had a drawback in that I could not spray in the house because of the smell/fumes, so it was build my own spray booth and install it in the shed. That in itself solved the spray problem, but then I had the problem of running an extension lead up to the shed, which is ok during sunny or cold weather but a no no when it is raining even though the cable is 'rubber' covered and the connection points are in the dry, don't fancy sparks emanating from my arris...
        But now thanks to YT, I have a solution that actually works and I can spray happily in doors, except for the noise of the extractor fan, but hey! that's what AC/DC are for....

          Not sure what you are driving at here Dave?

          I’ve used all sorts of primers over the years, including household primer undercoat in my more impecunious days. Always found car primer best for etched brass models because it sticks exceptionally well to sheet metal. It was my go to back in the day when all you could get was Humbrol paint. Cellulose knife stopping was a great filler to use with it as well. Not really used car paint since they went acrylic though as I find the cans lay down too much paint too quickly.

          I currently use the Vallejo acrylic for the little blokes. Sticks well, holding up under handling (the little blokes are gaming figures so are made to be handled) goes on flat, and covers ok. No problem spraying it if it’s diluted a bit with airbrush thinner and has a few drops of flow improver added, just like any other acrylic paint. Can be brush painted as well, which is something I sometimes do if I miss a patch when batch spraying. Takes a good twenty four hours to dry properly though, unusual for an acrylic.

          Dont use it for things like tanks, aircraft or cars though because I find I can’t sand it to a feather edge if I need to do remedial work once the primer is on. It just tears under sanding, even if carried out wet.

          Always wanted to use stynylres but on the rare times I‘ve needed to top up with primer I can’t find it for sale. If it is an acrylic primer that sands when dry then it could become my go-to, but I’ll reserve judgement until I’ve tried it.

            Never condemned any paints bar Airfix / Humbrol enamels from the 1980s and the horrible paints they have in their starter kits.
            Not sure why you think people are ''forcing'' you to change.

            You complain about people saying that they shouldn't say one is worse than the other, and appear to then do the same yourself.

              I am really glad it works for you Dave and, of course, if you cannot have a dedicated modelling space and extractor booth, water based acrylics would be ideal.

              I don’t agree that people condemn water based acrylic primers as such. Stynylrez and its ‘white labelled’ cousins like One Shot, work very well. I actually have some, though I don’t use it often (I did use it on my Merlin’s…). Vallejo primer though does have a well deserved bad reputation, I did make it work for years until I found Stynylrez, but it was always problematical with it vulnerability to humidity.

              If you can have a dedicated space though, with a decent extractor, I do recommend acrylic lacquers as they are well worth a small extra cost for their faultless and forgiving performance.

                It's all a matter of choice, I like many started with Vallejo primer. Eventually dumping the lot.
                Moved ,as I was unhappy with the contant blocking on the ab even though I tried more thinners, extender, newts blood , and blood of bat so used AK 3rd gen.That was brilliant. Then found black , grey and white MrHobby, even better .

                  Well for me, as a newbie to this building lark. I started with acrylic primer. Had some issues when first starting to use but after some reading and advice from the chaps on here regards pressures and mix. I've had no issues, even less with the new airbrush!
                  Never used a can and have no intentions of using unless something radical changes. Goes down to horses for courses again!!

                      Yes it takes a certain amount of working it your own way but as you say no issues once confident with the product

                            I will agree with your comment, if you have not tried it then how can you be critical or positive, as you say horses for courses. And if we were all using the same paint aka back in the dark days of Humbrol, then the ugly head of 'is that colour accurate would start again...'

                              My only beef with SOME acrylic primers are they are to soft and or i got masking peel. So I avoid that one and use another.
