Not so very green

The whitening effect can also be the reaction of putting an alcohol wash over DullCote. Sometimes the effect is good, but other times it ruins things. Luckily it can be reversed with another application of DullCote.

Unless the alcohol approaches full strength, it should not have any major effect on the paint job. Resist the temptation to continue work on the car until Otis dry just in case the paint has softened slightly.

Dullcote/alcohol reaction is very variable in result. Sometimes, it looks perfect, sometimes not. It depends on how the dullcote layer was sprayed. Spraying an alcohol mixture also calls for different reaction patterns. Mike Rose was using it extensively as a weathering agent. I'm actually experimenting with oil paints and mineral spirit washes and find them easier to work with. You can alter them after they are applied and using with care Titanium white fade perfectly bright colors. When dry, I dullcote them and carry on with other effects.

Reinhard: I recently experimented a similar reaction between paint and alcohol and didn't used dullcote. I can't explain what happened exactly. For dilution purpose, I recommend using 70% alcohol. 90% is far too strong for this application and could affect the paint layers receiving the wash. All you want is alcohol property to break water surface tension. As FCIN said, 90% is better for stripping purposes. 70% alcohol is the modeller's best friend.
