Is it possible to jolly up the black plastic parts by painting them? If so, what paint works?
Cheers.

Hi BooG,
I've just painted a black indicator housing white!

You'll just need some brand of plastic primer for starters and then I would use Plastikote for black parts, but for the matching white I had to use acrylic car rattle cans (Halfords). Probably most paints would be OK, but I would avoid cellulose paints on plastic.

I picked up this tip from another forum, although I can't locate the original source right at the moment. Instead of painting, it is possible to restore sun faded plastic to its original look using a mixture of 2 parts paint thinner to 1 part boiled linseed oil. Rub the mixture into the plastic and wipe off any excess. The plastic will be restored to original black colour with appropriate sheen.

I wonder how long it lasts. I worked in a boat place and the saledman used to rub the fibreglass boats down with Johnsons Baby Oil and wow what a smooth looking finish but it only lasted about 3-4 weeks and back to dull and chalky finish but by then he had their money.

It should last longer than 3-4 weeks. The linseed oil will dry to a film; baby oil won't create such a film. Better than linseed oil would be tung oil. It is one of the ingredients of varnish and will produce a more durable film. The thinners help the oil penetrate the plastic. I've done plastic restoration on some of my K75 parts using Liberon furniture oil that I had to hand and can attest that it does work.

I've seen the hot-air gun treatment but prefer something less aggressive.

My method is remove the discoloured surface as you would with paint. I use a cutting compound:

Then a polish that doesn't turn white or milky on plastic. The two that I've found to safely avoid turning black plastic grey are Mer and my preference now, Autoglym Aquawax:
