Okay making recommendations for others to paint their projects gets iffy. While I know what I would do, I also know what my prep work and abilities are and I have the proper equipment to apply such a finish. But not knowing those things or seeing (in person) the actual project makes suggestions questionable at best. I will say this, whatever paint you decide to use, the true actual finish seriously depends on the proper prep work of the surface you are painting. Don't think that even small scratches will be covered up with the paint coat. It doesn't work that way. If you have any imperfections on the prep effort, it will show up in the final finish for certain. And the second issue is to use totally compatible products in your selection of methods. In other words don't use a primer from one manufacture and a paint from another UNLESS you know absolutely that they will work together. It is easier to stick with one manufacture for everything. That way you know their produces will work with reach other without any issues. And I would most certainly use a hardener in whatever paint produce you chose. Hardeners will protect the finish better then any paint without. And hardeners will usually bring out a shinier finish as well. All I can say is that I like PPG automotive paints and clear coats. But That is just my opinion. And I'm not stating that it would be the best for your project...because I honestly don't know that it would be the best! JMHO!
