Stupid modeling tricks-- Dullcote + CA glue = white mess
Posted by BLACKSMITHN on Monday, August 24, 2015 8:13 PM

So, I just completed a beautiful flat car loaded with Oshkosh M-ATVs. I went to put a final coat of Dullcote on it before insuring that the CA I used to apply tie down chains was fully dried. The Dullcote turned the glue white! Did I just ruin my model? Any chance of fixing or saving it?

Hello!

Basically you have two options - one is to take the coat down, and put on a new layer, and the second would be to try to soak those white places with something to make the layer transparent again - I was once able to save my figs thet turned white after putting a flat clear coat on them. To see if it has a chance of success, try brushing on some mild solvent - like Mr Colour Thinner from Gunze, or Humbrol paint thinner - if the flat clear turns translucent but gets white again after the thinner dries, the places can be saved - just take a clear varnish, thin it 50 - 50 and brush it on. If the thinner itself doesn't help, then you have to take the coat down and put on a new one. Hope it helps, good luck with your project and have a nice day

You could try to soften the CA and remove it. Use nail varnish remover and some cheap brushes you dont mind destroying. Gently dab it on and lift the CA off but it could take a while and dont rush or you will loose the Dullcote in that area. I'd be tempted to glue the tie downs with Dullcote after so you dont get the issues again

You could try brushing on denatured alcohol. It works quite well for removing CA "frost" from canopies, so it might have some benefit in this case.

I managed to salvage the piece with a combination of a second coat of a different brand of matte clear coat, which took away many of the white spots, and touching up the remaining spots with Vallejo Saddle Brown, which dried out as a dark rust color. Thanks to all for your suggestions!
