Any finish that you apply is only as good as the preparation work. To do it right, you'll have to 100% disassemble and abrasive blast each part that is getting the new finish. I've never used duracoat (and refuse to!) so I don't know how messy it is. Any finish that you have to cook to cure, will produce fumes and smells. That may not be a problem for you but remember: In this day and age, strange "chemically" smells coming out of an apartment will cause curiousity and maybe even bring the cops. Keep yer powder dry, Mac.
