I was hoping someone may have come across this before, and know the best way forward.
I am building a DC kits model of 89001, and at the same time, repainting a Hornby CL82 DVT to match. The 89 was primed with Mr Resin, and then I airbrushed both with an undercoat of Humbrol light gray, so they would match. I then airbrushed Phoenix Precision GNER red, masked the red line off, and followed with GNER dark blue, built up over three or four coats.
For the lining, I used GNER red in a bow pen on clear transfer sheet, because I dont trust myself with a bow pen on the curves around the cab area of either model.
Transfers were from DC kits, with the warning flashes from Modelmaster. I used Microscale Microsol and Microset to help the decals bed down (and it was at this point, I relaised the "GNER" logo is a different size on 89001 compared to the DVT's... but that's life!)
Once that was done, I needed to clean up the models before I top coated with varish, and that's where my problem started.
I immersed the 82 in tepid warm soapy water to removed the marks the puddled decal soloutions had left on the dark blue paint, and as the it air dried, the surface took on a white bloom. I rinsed it again with water, thinking it was something to do with the soap, but it has remained.

Knowing I had to clean it up somehow anyway, I took a chance on the 89, and went ahead and did exactly the same thing to it - but it came away unscathed.

Thinking it might be the Microscale product, and needing a stronger cleaning agent, I carefully tried neat isopropyl alcohol. If I apply this to the surface, the bloom disappears - but as the alcohol evporates, the bloom returns.
Has anyone experienced this before, and if so, is there a way to salvage the DVT?
