My Dell Latitude 7280 has a similar rubbery coating both inside and out, and the keyboard is really nice, similar to Thinkpad keyboards I remember from the past. It’s also got a magnesium chassis, and seems to be quite durable.

I read a bit more of your comments before posting and it seems like you’re looking for a new, more powerful laptop… At least that exact Latitude model is a few years old, and low-power (and small, only 12" screen), but I’ll leave it here as an interesting note. I use it as a field-capture device for my astrophotography camera that can be powered by a big USB C power bank. Works great for that use, and is small thin and light.
