I hope someone here can have a good idea about a disaster that struck me yesterday.
I have brush painted my 1/72 Airfix sea fury including b/w identification stripes, in Extracrylic extra dark sea grey, Tamiya sky, Tamiya flat white and Tamiya flat black.
After leaving the kit for 4 or 5 days to fully dry off, I started to brush varnish it with undiluted Windsor and Newton galleria gloss varnish.
No effect on the extra dark sea grey, sky or white, but it instantly appeared to dissolve the flat black and left it smearing across the white stripes.
I stopped as soon as I saw the black smearing, tried to dab as much of the black smeared varnish off with IPA as I could, and then put the kit into the airing cupboard for 24 hours to see if it dried.
It did, and yesterday I repainted the worst affected white stripes, putting it back into the airing cupboard.
Now I would like to gloss varnish before putting the decals on; so I am wondering if the collective brain of the Britmodeller massive might have an idea as to why the varnish affected the Tamiya flat black, and then obviously any recommendations for gloss varnish that might not dissolve (I think that's what happened) the Tamiya flat black.
