I got the exact same primer from John at Scale Model Shop and I've always given it a good old shake first, I always put a few drops of Vallejo thinner in first but I've never had to go as low as 30/50 thinned ( I always kep a cotton tip with thinner to clean the end ( but I'm sure you know this


Now you are a seasoned modeller compared to my meagre skills and advice, but I have heard of other Vallejo primers going off from time to time ( grey primer I think )


I'm sure your supplier if he's any decency should give you a full if partial refund, possible offering you replacement?


The only other suggest is is there a blockage in your A/b ( please don't shoot me for sounding dumb)


Kind regards


Robert

try


1. thinning with Windex, or


2. thinning with Windex + two or three drops of Paint Retarder (I am using Liquitex)


It works for me, but I am living in a tropical country, so the moisture level may play a part too.

and to make things even worse than they were I,bent my needle cleaning the thing,


so I need to find some were to get cheap needles for a cheapo AB,:mad::mad::mad:

I use these primers most of the time but they can be troublesome at times. I have heard that as you get to about 50% of the bottle, too much shaking can cause it to permenantly thicken into a mousse like texture. I must admit, I have had days when I just could not spray the stuff and others, thankfully mostly, it works like a dream.


I have tried most thinners with it over the years and have found scream wash to be the most consistent.

You should have just sent Vallejo a message and they would have changed it Monica it may be a little late now you've thinned it but just let them know you never know they may just send you a new bottle.

it was a troublesome bottle from the start Graham,and should of done some think right away about it,


it did thicken,more like soup,and not a mousse,but still,


so do you still shake the bottle or not and how do you know for how long ?


and that just makes it a bit hard as to how long of a shake,as it dose Seattle to the bottom


was just a pain and in the end cost me more and I have to get a another AB,and wait,


for up to 4 wks, for it to come from HK,could try the needles but they may not fit so ;)

I did think of that Ian,before I got to thinking why not try the chap I,got it off,and see what


he will do about it,and he did give me a new bottle so it got me out of trouble,so I


will use that one and then just use the 60ml ones,after that,


I did try to contact dragon once about missing parts and never got an answer from them about it , ;)

I do still shake them but quite gently. I also use an electric mixer, Trumpeter I think. This stirs it up nicely without aerating too much. Not long enough for the big bottles but fine for the smaller ones.

If you ever have problems with Vallejo, contact them via their web site and give them the batch number from the bottle. It could be one of the iffy ones and they will replace it.


As for thinners, splash out on a bottle of their airbrush thinners and use that. It's made for the job.

About a year ago I had terrible persistent trouble with blocking of the nozzle (I have a good quality Harder and Steenbeck AB) using Vallejo Model Air paint (not primer). I shook the bottles, which had a rattler in the form of small stainless steel nut. Even reaming the nozzle did not help. I poured Model Air paint into a container and then from it into the cup, watching for lumps. It was so bad I had to buy a new needle and nozzle. I haven't done much airbrushing since but perhaps the problem has gone away. It might have been caused by the fact that I has sprayed Tamiya lacquer (solvent is Cellulose Thinners). Although the good quality seals were not affected, I won't do that again. I have yet to try Vallejo's Flow Improver (John's shop sells it).


In fact, if I am painting something which does not need the smooth finish of an AB, like a rust or dirt effect or a bumpy surface, I use a brush. Very quick overall and simple cleaning afterwards.

I use tap water to thin. Never had a problem with Vallejo primer and I use it on everything. Good luck getting this sorted Monica.

For what it's worth I am going to do a video soon about my experiences with Vallejo products. I hate to type so that is my alternative. Here is an excerpt from a p.m. I had with someone on a different forum that kind of roughs out what I have found pertaining to the paint, and probably covers the primer as well.


Oddly enough, as for me, the primer hasn't given me any problems. I have posted a few times on various forums (here too maybe) about my opinion concerning all of the additives and special potions one has to use to get some products to work. I find it annoying that stuff doesn't work out of the bottle. At worst a need to thin something a bit with the manufacturers own thinner should be all that's necessary. Flow enhancers, retarders, window cleaner, armadillo urine mixed with wombat saliva... just seems like a lot of hassle.


"Interesting. You have suffered the exact same situation as me. I will predict that the MM Acryl will spray fine, as mine did. I am pretty meticulous about airbrush care, and had the same problem with the Vallejo, but not the MM Acryl. When I back flushed my new Badger 105 Patriot during the first spray job where clogging was taking place, a glob came out. (And I always spray cleaner through a new airbrush before the first paint goes in in case there are any oils or anything present.)


As for the scum on top, let me know what you find. I am going to guess that it will be fine on top, though. I opened a bottle once and it was nice and liquidy (is that a word!?) I think the problem lies in over mixing. Other than the paint getting a little thicker near the bottom as it gets used up, the paint worked fine until I added an agitator. Vallejo's recommendation is to roll the bottle between your hands to mix the paint, which didn't make a lick of sense... until now. I have read that shaking acrylic paint introduces air bubbles into the paint in excess, causing minute curing of little bits of paint. It can happen to enamels as well, just not as bad. This thickens the paint a bit. I think Paul Budzig comments on this in one of his videos. I have used my Badger paint stirrer/mixer in the MM Acryl with no problems (yet). I think this works because the mixing part of the Badger mixer is inside the paint getting the thicker material off the bottom without introducing air as it is mixed. When I shake the Vallejo paint and open it, it is bubbly, as you mentioned. The MM Acryl mixed with the Badger mixer is not bubbly at all, since mixing happens below the surface.


What I think is happening is this:


1. Shaking the paint, as opposed to "rolling" the bottle introduces air into the paint, thereby causing it to thicken and/or dry prematurely


2. The agitator is loosening the "boogers" that cling to the sides and bottom of the bottle, whether it be dried paint (on the sides) or ultra thick pigment that just won't mix, on the bottom. I am thinking the latter is the real culprit.


I have a paint job on a tank coming up soon, so I will give one of the Panzer colors from the Model Air line a try. I haven't put a, agitator in it and I am going to try the roll-between-your-hands method and see what happens.


The only other solution I can come up with is to strain the paint somehow before it is added to the cup. I am going to try and Irish-rig something using a faucet aerator. The screen in those is pretty fine, but rigid, so I think it wouldn't be too much of a hassle to make something handy."


I will let you all know when I do the video, which will be soon, so you can watch if you want.
