I remember when I stumbled & bumbled into the Dullcote/Alcohol haze reaction. I had just completed a building model and applied Dullcote. I placed it on the layout and was applying ground cover to blend it in and grabbed my spray bottle with rubbing alcohol to wet everything out, of course spraying the building down. OH SH!T... everything turned milky white!!! I panicked and grabbed my weathering chalks to try and salvage it, but to no avail... But when it dried, like magic the grayish painted “metal” roof & siding suddenly looked exactly like old galvanized metal. Hmmm...
Had a lot of compliments on my “skillful” weathering techniques on that building. All due to dumb luck.
