Protection spray paint for ABS cap (to avoid 'shine' and wear)
« on: Thu, 20 October 2016, 06:48:27 »
There are keyboards in the past and now that I am letting them sit in storage because I don't want to create any wear and shine on their ABS key caps. I'm thinking if I can do anything like an invisible protective spray paint on these ABS caps so that the 'shine' can be avoided and I can rest my mind and start trying these keyboards out more often.

Has it been done before?

Just use them and get over it, embrace the shine.

Life shouldn't be this complicated. :P

But of all the coatings I've seen none have been very long lasting and only make things worse.

All coatings wear.  There isn't a clear coat you could put on a key cap that wouldn't wear off and look worse than if you'd just left it natural.

And the disparity between the more worn ones and less worn ones will be amplified.

“Any split that is higher than 5%,” the letter states, “will be seen favorably by the RNC and President Trump's campaign and is routinely reported to the highest levels of leadership within both organizations.”"

There are a few things you can do, actually.

You can sandblast them with a very fine grit, deskthority thread here: https://deskthority.net/workshop-f7/keycap-sand-blasting-t12946-30.html

Or if you're fixed on coating them, there are some interesting two-part epoxy lacquers designed specifically for abrasion resistance, used for example in marine engineering. You should research, but here is one example: http://www.hempel.com/en/products/hempadur-15590

These should be overkill enough :)

ABS is reactive with solvents, though, so some resins can damage its surface. Make tests, pre-coat with acrylic, etc.
