help my sanity-- spray paint troubles
Mike wrote: I have 2 flat metal parts made out of steel. I want to paint them flat black. I was recommended Rust-o-Leum 7777 as a perfect match for the paint color and finish. I first stripped the old paint with a spray-on stripper and than spray painted. Looked great, but I wasn't pleased with how hard the finish was. It scratched with my finger-nail. Rustoleum dries particularly slowly. If you have a "hot box" or oven you could bake the painted pieces in for a couple of days, you will go from "soft finish" to "hard as it'll get". It still won't be as hard as powder coat etc. I re-read the directions and realized I did *not* use primer. Of course I was ****ed off, but I decided to redo everything. I stripped the paint again using the same, nasty spray-on stuff. I then rinsed with water, and used a wire-brush attached to my electric drill to get most of the old stuff off. I then wiped it down with a wet rag and let dry. This time I used Rust-o-leum primer first, then applied the same spray paint. But it seems the finish is even softer than before. There are a lot of different primers available. Generally there's more paint to dry with two coats and it'll be softer for longer. Tim. |
