I was finishing up my jagdpanther - a little more wash, some drybrush. Looking pretty good I thought. There was a little bit of shine on the hull area where I had brushed on some future prior to applying the decals....so I thought I'd lay a coat of Testor's Dull Cote for good measure. Some serious cracking going on here. I've not experienced this before. Can anyone tell me what the heck happened? Larry |

Testors dull cote is a lacquer based paint, thus "hotter" than enamels and acrylics. So what has happened is the underlying paint has softened and crazed due to the overcoat of dull cote.
It happened to me once using Aermaster flat coat thinned with Tamiya acrylic thinner spayed over Tamiya dark yellow. The thinner softened and reacted with the dark yellow. I was not impressed and I thin flat coat with distilled water now!
The unwritten rule is "LEA" (Lacquer/Enamel/Acrylic) You can alter that order but only using a good barrier coat. For example, Future over enamels in order to use oil washes. If you really want to use hotter paints over paints that could react, then apply multiple light coats to reduce the chance of the carrier reacting with the paint it is covering.
I have used both methods successfully on many occaisons, even with Tamiya spray can lacquers over Pollyscale/Vallejo acrylics.
Can you carefully repaint that section and re-weather at all?
