It should be noted that you can use all kinds of things that can work. I've used all kinds of incompatible materials and had it come out fine. But you are taking a chance when you do. I've used Dupli-color products in the past and it's worked fine. I've also had some problems with it. Any lacquer finish is going to be susceptible to temperatures, humidity and pressure. Urethanes not so much. It's a touch deal to guess and that's why Mark Scarborough and I often preach that you are better off to use materials that are designed to work together. Many folks have use Sig dope with Dupont 3608 and had great success. But these materials are specifically designed to work together so what you often get is a narrower window in which the stuff will cooperate. I finish planes in an area of very high humidity and marginal temps. As a result, it can get dicey trying to use products that ARE designed to work together. Were I finishing planes in Tucson, I wouldn't be as concerned.
You pays your money and takes your chances.
