Enamel can be thinned with lacquer thinner but lacquer can't be thinned with enamel reducer or it will curdle. Enamel will dry quicker and attract less dust when thinned with lacquer thinner but will dull quickly. I never trid using hardeners with lacquer. I worked at an independent body shop for a while in the 80s and we did quite a few all over paint jobs. Some people are tight and wanted-expected an Imron like paint job at an alkyd enamel price. We would use imron activator in the dulux dupont enamel and it would dry hard and resemble imron at a fraction of the price. Thats where I got the idea to try urethane activator with rustoleum. If the conditions are right and the correct temp urethane reducer is used it worked out good for me . After the paint had set, we hand rubbed it the next day to give it a rubbed out lacquer look.
