I like this.

Remember half those issues are just common faults with cars of this age. Paint will fade, incandescent bulbs will blow.

But for me, the wiper arm paint coming off, I just unbolted mine (see workshop manual) and sprayed black spray paint on it (removed wiper blade first). If that doesn't work, I'll just repaint it

I haven't had issues with my washer bottle. But it's easy enough to go to a wreckers and grab one. $20 tops.

The most common blowing bulb in the dash is the "D" light because it's been illuminated for 99% of it's life. If it blows, swap it with any of the other lights. P and L are common.
