Almost all ‘57 Chevy models, whether they are plastic or die-cast, come with a chrome plated front bumper.
I give you exhibit A:
STEP 1: I always paint the grille ‘mesh’ gold. (Side point, some of you may not be aware, but on a 1957 Chevrolet Bel Air the grille was gold.) Now, I always use an acrylic so that I can easily rub the paint off of places I didn’t want any gold. These grilles are kind of tricky to mask so I don’t bother on smaller ones. I don’t know if it’s just that I use cheap paints but they really seem to get gummy when painting......
STEP 2: Blacking the squares inside the mesh is done with a black wash. I use the one from Tamiya but I’m sure any companies will do. Unfortunately, this step really depends on how deep the grille was molded and how thickly you applied the gold in the first step.
Now you should note, a lot of the gold got lost on this grille because of the aforementioned reasons but I still think it turned out pretty well especially the center badge!! I used VERY thin gold bare metal foil to do the lines in the emblem, this was the first time I ever tried this technique and I think it worked pretty well.
Of course, on this example I also painted the turn-signal/ running lights, dagmars, and front license plate.
Here are some other examples of grilles I detailed:
This one was very large, 1:12 scale and I did mask and then had to use black paint in the top squares that are not full boxed in because the black wash would just flow out.
This one is 1/16 scale and the top was removed to fit a body that it did not come from. This project is actually still pending from sometime last year as I just go busy with other models, I guess. Also I used black Sharpie as well as the wash and the it looks kind of brownish from certain angles.
M2 1:24 scale that was already gold and all I had to do was the black.
1:24 scale cheap Chines brand and the grille emblem was printed on my inkjet and hand cut.
1:24 scale M.A.S.K. vehicle. I had painted all the details on the center grille emblem as well. I was really surprised how well this one turned out considering how fine the mesh is.
This is the smallest 1:43 scale and the grille emblem was printed on my inkjet.
