Touching Up the Silver on HP35 / 45
Has anyone had a go at retouching the worn silver on classics?:

I've seen chrome and aluminium paint advertised, does anyone have any experience with this?

TIA,

Tim

RE: Touching Up the Silver on HP35 / 45
Use a silver leaf pen, like this one:

https://www.amazon.com/Krylon-K09902A00-...B00448INW6

It works remarkably well, though you must be careful and patient when applying it (to not touch elsewhere, leave an even amount, etc.) but you'll like the result. You can also carefully trim the writing wick with a razor knife if needed, or if it 'mushes' down.

Also, be sure to clean the area to be painted thoroughly to insure no grease, fingerprints, dust, etc. is there when you paint it. I suggest using a mild cleaner first, then follow-up with alcohol, but don't get alcohol on the bezel labels, it can remove the label paint.

If you try this, please post photos of the 'after' results so future readers will be able to see how well it works.

Credit for original idea (teaching me) goes to Didier Lachieze.

I like Krylon's Leafing Pen. It's pretty shiny and easy to apply. Test it on a scrap piece first to make sure it's what you want.

Cheers, Both!

Will give it a shot... pen application should be easier than a brush...

TIA,

Tim

Well, I will not claim the original idea as I was inspired by a post from 2006 from someone named Gordon. See here for more details

The Krylon works well, but not a shiny finish. Boo boos can be removed with a soft eraser if done quickly. Practice before you try it on a calculator.

Personally I would not use it on a seriously collectible calculator.

Another suggestion from a friend who builds model cars: Use bare metal foil. I've seen his models and you can't get shinier than that. You can actually see reflections in it. I watched him do some detailing one time and it looks fairly easy. You put the foil over a surface and rub it to completely bond it with the surface then trim off the excess. The result is amazing!
You don't have to worry about getting it on other parts. It only sticks to the part you rub.

Now that's interesting... I'll have to look into that...

RE: Touching Up the Silver on HP35 / 45
In my understanding, the foil is exactly what leafing is (anyone remember getting a CRC Handbook of Chemistry & Physics with the foil to put your name on it?).

In my opinion the various leafing pens work better if the desired color is more like aluminum; slightly on the bluish end of the spectrum. The actual silver leaf (foil) which you can also get at Michael’s, is a warmer hue; more like real chrome plating.

The foil is relatively fragile—it will rub off what you put on with only a little more effort than what you needed to transfer it in the first place, so it is not good for high wear areas unless it;s only a :display” calculator.

Fortunately, most of the calculators appear in those areas to use paint and so are more “aluminum-colored” to my eye.-kby

True. My friend didn't touch his display models much!

Whatever solution you go with, please pose an after picture here! The results should be interesting.

There's another product that looks nice and shiny.

Molotow liquid chrome pen

Haven't had any experience though, although I might give it a try.

cheers
