  • "The Metallica's" My MDF Trenched Boxes

    After attempting a brushed stainless finish I decided I wasn't comfortable taking a brush to the finish. Need more practice. So I decided to go with as much metallic as I could get in the paint. I painted these with this. I sprayed them with light fog coats until they were completely covered. Then I sprayed four back to back coats of Krylon crystal clear. I let them dry about 20 minutes between coats. I then let it dry 24 hours and sanded with 400 grit dry paper. I then sprayed a real light mist of the stainless steel paint to get some more metallic on the surface. This gives the metallic a lot of depth. Then I put two more back to back coats of crystal clear on. It was kind of hard to take pics to show how much metallic came out in the paint. Looks pretty cool.


    I will be putting the RS100-8/ ND20FA in them.

      Bravo... Those look stunning. I wonder what they would have looked like with a light mist of copper-metallic on the in-between coat. I may have to find out!!!! ;):D

              Dave,

              Those look awesome!
              I hope I am understanding you correctly, you used Rust-Oleum which I believe is a metal paint on an MDF cabinet then used Krylon and again I believe is a plastic paint on top of the Rust-Oleum? Did you have to prime the cabinet first? If so what did you use as a primer?

                I love the phase alignment. I may be wrong in this assumption, but the dip in responce between 2K and 5K is a good range to tame a bit and will give them the "listenable for hours" feature.

                  I'm not sure if it is a metal paint. I used this to prime with. The cabinets are so small they were pretty easy to spray. One thing I noticed the products in spray cans are a lot thinner then the automotive products I normally use. On the plus side I have a bathroom in the basement that I am going to be remodeling and it has a strong exhaust fan in it. So I kind of have a little spray both in the house.

                    Thanks, I believe the dip is called a BBC dip. I put it in my Mini Surround speakers and really like it.

                      Verrrry nice finish. I always have to go the other way, trying to find finishes that hide the shortcomings of my boxes. Your experiment seems to have worked quite well.

                        After the finish dried for a few days it seemed it soaked in some more and I really wasn't happy with it. I could have wet sanded and buffed, but I really didn't feel like doing it. So, I have been looking at the Parks Super Glaze at HD and have been wondering how it would work. It's basically a two part epoxy coating. I dry sanded the cabinets with 400 grit. Reading the instructions it says best dry conditions are at 70 degrees. My work area is around 60 degrees, so the finish was a little thick. I also accidentally didn't add enough hardener so it set up slow.
                        The shine came out beautiful. I should have warmed it up so it was thinner and could have applied it thinner. On flat surfaces the thick is fine because it flows, but on the sides it wanted to sag. Not putting in enough hardener made it set up slow which didn't help. All in all it came out ok. After they dry good I am going to sand them down and try a heated batch with more hardener to see if I can get it to flow smoother. I was flipping these around to keep the finish from running so the finish isn't flat on any one surface.
                        They do have a really nice deep clear smooth finish for applying with a sponge roller. If I can get the temp and thickness right this could make an awesome easy finish. It was $20 for the kit and I hardly used any on these small speakers

                              Thanks Mike, but this has got to be the easiest finish to apply to get an instant built up high gloss finish. On flat surfaces is would flow out like a mirror. Its the sides that it wants to run or sag. If all the edges were square you could do one side at a time and get an instant piano finish. I did some reading that says it can be sanded and polished, but I was wanting to avoid that. It is very difficult to get a true mirror finish without some hazing. Let alone the amount of work.

                              COOL!

                              You can brush this finish as well as pouring it.
                              In reading, this product can also be put over almost anything it says. If built up enough it would hide any imperfections in the finish. Basically all you need to do is get a color on the cabinets evenly. There is also plenty of working time with it. Basically the thicker you apply it the more heat that builds up and cures it faster. In the cup I mixed it in there was about a half inch left in it set up within and hour. The cabinets took about eight hours to set up. They recommend covering with something about 5" off the surface to keep dust off until it cures. Pretty interesting stuff.
                              I am also sensitized to epoxy and did not have any issues with this. I did wear Butyl rubber gloves and a vent fan running in the room.
