Yeah wicked is good at what it does, but you do not ever want to let it set up... like ever. I went to bed once forgetting to clean my Krome........ the words that came out of my mouth. I found denatured alchohol ok, but i often use my w 500 as a cleaner. While it seems expensive im still using a quart bottle from months ago. Buying reducer in quarts when chicago airbrush has a sale is like 20 bucks or so.
