I have a gallon of synthetic enamel paint , and acrylic hardner and acrylic enamel reducer. Is there a difference in acrylic enamel hardner and synthetic? IWhat will happen if I mix it and spray it on a vehicle?

You need to get equal parts of the synthetic enamel paint and acrylic enamel reducer. If you get the wrong mix it will be either too hard or soft. I hope that this helps. Also, you can check the label and see if it has service support.

Thanks for all the advice Big Liz. Are you a painter because it seems that you know a lot about paint. Plus, do you have a boyfriend because I'm weak for a woman in a painter's uniform? Lol
