A couple of us over on the mustang forums have had problems with the chassis black drying. We both used it over metal that had been primed with Rust Encapsulator. I used Extreme Chassis Black and the other fellow used the regular Chassis Black. After several days, it is still tacky and we’re at a loss as what to do. I sprayed mine right out of the can and did not dilute it, and as far as I know, it was stirred well. Any suggestions?
