grit in the creases

[tempestwulf]

I use laquer paints quite a bit now for major work and camo which looks great and gives beaut finish.

I recently brough Mr Colour/base 1200 (white) and it gives a good finish in general. Issue I'm having is there seems to be an amount of "grit"gathering in area's like the wingroot curve, landing gear bays, tailplane roots etc.

I'm thinking I'm using to high a pressure or have the airbrush to far away from the model. don't have issues with the dilution thinning ration as got that sorted a while back.

Any ideas?

Hi there

I know exactly what that is as I have gone through the same thing.

You are right, Mr Color Laquer is amazing paint to say the least.......everone should use it!

Anyway, you are correct. It is pressure. I struck it on my Tamiya 48th Corsair (on this website) on the wheel wells and around the rocket stubs.

You will have to rub it down smooth again obviously. This time wind the pressure right down, I also found that a couple of extra drops of thinner will help but not necessary. Also keep the nozzle of the brush a lot closer. Just experiment a bit. But what it is, is the paint drying too fast and swirling around in cavities before settling on the surface. leaving a pebbly/gritty look.

Hope this helps

Hey Anthony

Thanks for that. Definately right on the type of paint and brand, awesome and speeds things up 2 fold. I'll try what you suggested when I'm painting my current 1/72 F6F, fortunately I purchased the white primer so it works as a sealant as well as the base colour.

Thanks for the help it's always appreciated.

You are more than welcome mate. Anytime

Now then chaps,

Its the old Faraday effect which manifests itself when spraying into corners. I agree with your approach Anthony of backing the pressure right of and thinning the paint a little more than usual. I try to anticipate areas which will be affected by this and blow some thin coats over these spots before sprying the main coats. For the most part this seems to give good results.

I use Aztek airbrushes and they make an 'acrylic paint nozzle, general purpose' which does not have a skirt around it and I have found this sprays well into awkward corners. Iwata do similar tips and I have seen similar tip arrangements on some other brands.

On another matter Tempestwulf. Hows the Eduard Tempest progressing.

[tempestwulf]

Ah yes the Eduard Tempest.

Well I got the cockpit together and weathered to my liking whilst trying a couple new techniques. (just got a digital cam via flybuys so will get pics).

Fuselage, wings, wheels, tail planes also together with seams sanded flat so only the major sub assemblies so far.

Not much thereafter since as stashed it on the back burner while completing a few 1/72 birds (DML Mig-15, Fujimi D4Y2 & Ju-87D - the latter being my best work to date).

Purchased a heap of new lacquer paints since completing the Hellcat and working well getting no if very minimal gritting. Have found removing the cap helps too. I find their colours accurate which is pleasing to the eye.
