I'm building an old Monogram "Mercedes Classic Coupe" from Monogram - it's a 540K. Has anybody ever built one of these, or the roadster version?
There's there are a couple of things that really have me stumped.
1) I can't figure out where to mount the fan/belt/pulley assembly. The instructions don't show it clearly. The one-piece fanbelt assembly has two holes on the back. One is behind the pulley, and it logically would fit over a pin on the front of the camshaft housing. But there's NO MATCHING PIN for the hole on the back of the fan. There's a 1/16" gap between the fan and the front cover. Makes no sense; it just hangs out there. How is the assembly supposed to be attached to the front of the motor?
2) There's a similar problem with the cam/intake manifold assembly. The two ends of the u-shaped manifold tube seem intended to fit into holes in the block, but there aren't any holes for it! How does that little assembly attach to the block? Seems unlikely they'd want the modeler to drill holes to mount a part.
I've got photos of the engines on real 540k's, but nothing seems to match.
I try to use the mildest products that will do the job. Ordinary isopropyl alcohol will strip most chrome, and for paint, just about any strong degreaser - like Simple Green - will get 'er done. If I have to leave a part in the stuff overnight, that's no big deal. Sometimes it takes a brass brush to get residue out of the crevices; that's okay too.
I agree with everybody about using water-based acrylics over Alclad - and avoiding anything that has alcohol or lacquer thinner in it. The same applies to kit chrome.
Tamiya makes an acrylic called "Smoke" that will work. But I've run across something I like better. Future, aka "Pledge with Future for Floors," can be tinted with dye-based inks and used as a wash. Future is a water-based acrylic, so it's safe on Alclad and on kit chrome.
I like it better than the Tamiya clears because it's not as thick and you can adjust the tint. It's also glossy. The inks come in a range of colors, so you can use this method to tint headers blue, brown and orange. You can also blend colors by using a brush and dipping it into different mixes or clear Future.
I use dye-based inks. You can buy them at any art store. You can use ammonia to remove dried Future, but not from kit chrome. It dissolves it.
I actually like kit chrome pretty well when it's tinted with this method.
The time-honored rule is "Never ever put lacquer over enamel," but some of the hobby synthetic lacquers are pretty good that way. Nonetheless, I'd test a similarly painted part before risking the entire paint job.It's important not to spray it too wet. Lacquer thinner HATES enamel, and will make a big mess of it.
Actually, I think kit chrome looks pretty good, but ONLY IF it's "washed." I add acrylic ink from an art store to Future and dip the kit chrome pieces in it. A tissue is good for wicking off the excess.
I just tested Duplicolor spray chrome again, and tried rubbing my fingers on it, and it didn't tarnish. Maybe it tarnished because I used Tamiya polish on it. I tried painting some sprues with it, and they came out looking pretty good.
So... most people recommend either BMF or Alclad II. But only rarely does anybody recommend Duplicolor chrome. Why is that?
