Airfix 1/48 Hurricane Mk I

After me raving about the Vallejo Surface Primer a week or so ago I've had an issue with it in that trying to rub down the joints that needed filling, the primer has just peeled off;

It's as though there is no 'bite' to the primer whatsoever. I've since received some advice as to where I might have gone wrong (applying it too thickly instead of thinner coats, not letting it cure for a long enough period) so I will reserve judgement and experiment further on an test piece.
In the meantime I washed it all off using IPA (Iso Propyl Alcohol) and will go back to the Games Workshop rattle cans for now. I have to use white as the areas for the national markings will be masked off prior to painting as dark paints will only show through the decals.
Also the primer had to be removed as I'm not sure what reaction would occur between the Vallejo and putting the Games Workshop stuff over the top (probably a bad one knowing my luck).
Bugger.......

Edit;

After cleaning up the wing root joint again the model was sprayed with Games Workshop Corax White (which isn't white, more an off-white for some reason) and this time it's worked;

Now I can get on with applying masks for where the national markings will be and painting the thing. Finally!

Prime time for the Takom Leopard and Airfix Hurricane

Now that the Leopard had dried out and the Hurricane is up to the stage of being painted internally I primed both models using Vallejo's black Surface Primer. It's the first time I've used this stuff on current projects as I've only done tests on an old model but I do like it, I usually use Games Workshop rattle cans for priming but as I have to use it outside I'm at the mercy of the British weather so to have a good primer I can use through an airbrush is a big bonus.
The only downside is that being acrylic based I found I had to clean the needle a couple of times due to the build up of paint and at one point I had to clean the airbrush out as paint was starting to block the nozzle, however I can live with that if it means I can get stuff primed quicker rather than having to wait for a break in the weather. Also I shall try it again with acrylic retardant to see it that makes a difference;

 Oh and the Vallejo primer doesn't smell bad either so it's pretty family-friendly.
