In addition to what Jim said, I'll try to give some general guidelines, with basecoat, don't spray wet coats, let it flash a minimum of 30 to 45 minutes between coats. You aren't doing production work so you can afford to let it flash longer. With your clear don't let it flash longer than 30 minutes between coats. Longer you may run into issues. If you have some urethane retarder using 1 ounce per 32 ounces of RTS (ready to spray) clear will help offset excessive humidity. Reduce the Universal up to 10% as well.Jim I have extra slow activator and reducer. How much flash time do you recommend?
