Hi there,
I have a question about the paint of the Sanyo Monitors (VM 4092/ VM 4209). Like other surfaces that have a structured paint finish, it has the typical slighty rough feel to it. I happen to buy a 4092 in pretty rough condition regarding the optics. And although I could improve it, I was thinking about re-painting it.
My question: Does anybody know how the process would have been done back in the 70ies? Would it be a normal paint first (with the grey/yellowish tint) and THEN add another coating with clear structured paint or was this a "one coat" job with a colored structured paint?
Any insight is highly appreciated.
Happy New Year!
Armin
PS: I know, I know: Some will say "Just leave it as it is!" and I might do so. But there is another 4209 on its way and that one is in absolutely horrible condition. So I might want to restore that one completely including the paint job.
Although it may not be 100% and I have never tried before, you can look at wrinkle paint which is normally used on metals and was used on the sheet metal cases in the old day. VHT has a wrinkle paint series in spray can.
In the typewriter world many typewriters from the 1940s onward used so-called "crinkle paint". However, that paint texture is known to be almost impossible to replicate outside of an industrial setting, as it depends on a very specific combination of paint, temperatures, and timings.
I have seen videos of applications of newer spray-can crinkle paint, but usually the texture is very different (much coarser). It might work ok for an engine block, for example, but I don't know if this would work for your monitor.
I am almost certain that what Armin is describing is different from the crinkle paint found on old typewriters. I will see if I can find some photographs that show the difference, so we can move forward knowing what we are talking about.
I have a bit more info now: I brought two housings (one 4092, one 4209) to a professional industrial painter (or whatever you call those guys … :-)
He looked at the housings and said: This is no wrinkle paint or any kind of structured paint for that matter, it is just a sub-par paint job. He also ruled out a powder coating paint job, just normal paint varnish. He said that if you just spray paint metal and do nothing else it will come out this way.
So he is giving both cases now a new paint job and they should come out just how they are now just without the wear, scratches etc. I will send pictures when I get them back.
In the meantime I will try to re-create the brand label that is missing on the VM-4092 unless somebody knows where to get a replacement. Not sure how that could possibly have fallen off, but it was missing. I reckon it is a 0.5mm aluminium plaque. Will try to find somebody that cuts me the right shape, then paint it black and laser the logo out of the color.
Best
Armin
