stupid question about color

[Nexx]

I have made some plane models kit when I was young, and the model who are paint in white (with Tamiya air spray TS 27 white matt), like a rafale. After three or six months, the white has turn yellow !

How do you protect your model kit color ? I have 9 valkyries models kit who require white and I don't wan't that happen again.

I think of use another color, like grey for 5 of them (3 skull leader and 2 hikaru's vf-1J), but I think that's was not very good looking for vf 11 (macross 7 style) and a vf2ss.

Thank you for your help.

It depends on the base for the color. Alot of companies used to use lead for it which really yellows after a time. Most companies use Aluminum now or titanium in their paints which yeild a whiter color with less yelow in it.

Use top coat.

Mr Super Clear can spray now comes with an anti-UV type. I'm not sure how effective it is, but definitely worth a shot.

Available in gloss or flat.

Man that was a stupid question, I've heard some whoppers in my time but that one takes the cake. ha ha, just kidding.

Actually the yellowing of white paint has been the long time enemy of many a modeler. I don't know if the white paint you used is acrylic based or oil based but oil based paints tend to yellow more. I actually have only had yellowing problems with my oil paints I've used not the acrylics. The only other suggestion I have would be to keep them out of the sunlight as much as possible.

Good luck

The most surprizing thing is that the model of rafale is stay in a box after I build it...

Thank you all for your answser. I will choose carefully the paint, and also use the antiUV. Anyway, all my toys and model aren't expose to a direct sunlight.

Surprisingly, sunlight can UN-yellow many things. According to LEGO, white Legos turn yellowish when exposed to INDIRECT light, and leaving them in the sun will whiten them. I need to try it, I have some old white ones that are very yellow in spots.

Also, yellowed decals can be helped by exposure to sunlight for a while. I've tried it myself and it worked.

So maybe people need to stop leaving their models indoors, behind glass, and leave them out in the sunshine.

PS--the problem with models is always trying to determine what yellowed. Was it the white paint, or was it the clear coat? Sometimes it's both.

Testors Dullcote is particularly notorious for yellowing over time. I've had a white Gundam coated in Dullcote that was so yellow that it matched the yellow chest vents.

Well, maybe not quite that bad, but it was pretty yellow.

hmmm... not stupid at all!

I use Tamiya XF-2 flat white for all my top coat. I built a Scimitar in UN white scheme about 5 years ago... still white! Tamiya's flat white is the only one I know that doesn't yellow over time, try it, you'll like it!

Cheers

amazing, I must try that

Thank's, I will ask information in my model shop for Tamiya XF-2 frieday. Is there in air spray ?

[johnybgood18]

hmmm... that's the catch... I know about the XF-2 in bottle ( I use an airbrush) but I'm unaware of the spray can and if it might yellow or not! Maybe someone can provide info on that?

Cheers
