I have some of Frank Badelson's engine paint to spray. Its a acrylic enamel paint. I have two questions.
Q1- Tech sheet specifies usnig the DTR reducers per the temperature, I have some DT870 on hand can I substitute the two. The DTR reducers are Acrylic Enamel reducers but the can of DT does not say for use with this type of paint.
Q2- The mix ratio is color 8 - reducer 3 and hardener 1. The supplier of the paint said do not use the hardener it will be too shiny. So question is how do I modify the mix ratio. Do I just substitute the hardner with reducer?

Thanks for the help, I am really new at this painting stuff
